With the development of electronic technology, each existing application is more or less combined by some objects that need to communicate messages with each other to complete the task.
The conventional event notification generally performs corresponding event message processing by sending a message notification to different pages or controls when the pages or controls are alive. At present, a conventional event message processing mechanism (for example, a famous open source project EventBus) is generally only good at processing a scene that an event source is on other pages, and a main page receives an event transmission message, for example, a scene that each article shows a praise amount of information in a project top page list, and after clicking to enter a news article page in the list and carrying out praise operation in the article page, the project top page needs to be updated with the praise amount, wherein the event source is the article page, and the main page is the project top page which needs to receive a praise change event of the article page.
Because the traditional event message processing mechanism is only good at processing the scene that the event source is at the sub-page and the main page receives the event delivery message of the sub-page, the traditional event message processing mechanism can only work under the condition that both the associated page and the associated page are alive, but for the condition that the associated page is not created, the event 1 of the associated page changes and notifies the associated page of the event change, or the associated page receives the notification that the event changes, but the condition that the associated page is destroyed cannot play a role in message delivery, and therefore, the defects that the event notification cannot be delivered between the associated page and the event cannot be synchronized exist.

The principles and spirit of the present invention are explained in detail below with reference to several representative embodiments of the invention.
Summary of The Invention
The inventor finds that if the coupling degree between the associated page and the associated page is reduced, that is, the associated page and the associated page do not directly exchange the transfer message, but an intermediary device stores the notification of the change of the event sent by the associated page, and sends the notification of the change of the event to the associated page, the requirement that the associated page needs to survive when the associated page receives the notification and the associated page needs to survive when the associated page sends the notification can be eliminated, thereby effectively reducing the requirement of event transfer and improving the inclusion of event processing.
Having described the general principles of the invention, various non-limiting embodiments of the invention are described in detail below.
Application scene overview
Reference is first made to fig. 1.
Fig. 1 schematically shows an application scenario of an event processing method, apparatus, medium, and computer device according to an embodiment of the present invention. It should be noted that fig. 1 is only an example of an application scenario in which the embodiment of the present invention may be applied to help those skilled in the art understand the technical content of the present invention, and does not mean that the embodiment of the present invention may not be applied to other devices, systems, environments or scenarios.
As shown in fig. 1, the application scenario 100 includes an intermediary device 110, an associated page 120, and an associated page 130.
The intermediary apparatus 110 may specifically be, for example, an electronic device capable of receiving a notification of a change of an event sent by the associated page and sending a notification of a change of an intercepted event to the associated page 130, where the electronic device includes, but is not limited to, a desktop computer 111, a laptop portable computer 112, a tablet computer 113, a smart phone, and the like.
The associated page 130 and the associated page 120 may be, for example, display pages of the same other electronic device or two different other electronic devices except the mediation device 110.
The intermediary device 110 may be a functional module stored in an electronic device such as a desktop computer 111, a laptop computer 112, a tablet computer 113, and a smart phone in fig. 1.
The associated page 120 and the associated page 130 may also be different pages displayed by referring to the electronic devices such as the desktop computer 111, the laptop portable computer 112, the tablet computer 113, and the smartphone in fig. 1, and the associated page 120 and the associated page 130 have an association relationship, specifically, the association relationship may be that, for example, part of content in the associated page 120 changes, which may cause corresponding content in the associated page 130 to change.
Specifically, as shown in fig. 1, the association page 131 and the associated page 121 have an association relationship due to the change event 2 and the change event 3, the association page 132 has an association relationship due to the change event 1 and the associated page 121, has an association relationship due to the change events 4 and 5 and the associated page 122, and the association page 133 has an association relationship due to the change event 4 and the associated page 122.
The intermediary device 110 is configured to receive and store change events 1-5 (specifically, notifications of event changes) sent by the associated page 120, and receive an event subscription of the associated page 130, specifically, subscription information provided by the associated page 130, and establish a monitoring mechanism of the associated page 130.
The notification of the event change sent by the associated page 120 includes the identifier of the event that has changed, and the subscription information provided by the associated page also includes the identifier of the event that needs to be monitored, so that when the associated page 130 needs to synchronize the monitored event, it can be determined whether the received notification of the event change includes the event monitored by the associated page 130 only by the intermediary device 110 recalling the subscription information provided by the associated page 130, and in the case of including the event monitored by the associated page 130, the intermediary device 110 sends the notification of the event change monitored by the associated page 130, thereby implementing synchronization of the monitored event, and implementing the transmission of the change event between the associated page and the associated page.
In summary, when receiving the notification sent by the associated page 120, the intermediary device 110 does not need to consider whether the associated page 130 is established, and when sending the notification to the associated page 130, the intermediary device 110 does not need to consider whether the associated page 120 still survives, so that the coupling degree between the associated page 120 and the associated page 130 can be reduced, and the delivery mechanism of the notification with the event change can be applied to more specific scenarios.
It should be noted that the event processing method provided by the embodiment of the present invention may be executed by the intermediary apparatus 110. Accordingly, the event processing apparatus provided by the embodiment of the present invention may be the intermediary apparatus in fig. 1, or a functional module disposed in the electronic device.
It should be understood that the number and types of intermediary devices, associated pages, and associated pages in FIG. 1 are merely illustrative. There may be any number and type of intermediary devices, associated pages, and associated pages, as desired for the implementation.
Exemplary method
The following describes an event processing method according to an exemplary embodiment of the present invention with reference to fig. 2 to 5 in conjunction with the application scenario of fig. 1. It should be noted that the above application scenarios are merely illustrated for the convenience of understanding the spirit and principles of the present invention, and the embodiments of the present invention are not limited in this respect. Rather, embodiments of the present invention may be applied to any scenario where applicable.
Fig. 2 schematically shows a flow chart of an event handling method according to an embodiment of the invention.
As shown in fig. 2, the event processing method according to an embodiment of the present invention includes operations S210 to S230, and the event processing method may be performed, for example, by referring to the mediation apparatus 110 in fig. 1.
In operation S210, a notification that the event sent by the associated page is changed is received.
According to the embodiment of the present invention, the associated page, for example, at the time of initialization, may directly send the identifications of the events subscribed to by all the associated pages, for the intermediary apparatus 110 to receive and store in the preset event identification hash set, and for different events, the identifications may be unique, for example, eventID, specifically, the initial state of the preset event identification hash set is an empty hash set state. The associated page may also include an identifier of the event that has changed in the notification of the change in the sent event, and the associated page is stored in a preset event identifier hash set when the intermediary device receives the event identifier.
According to an embodiment of the present invention, the above-mentioned associated pages may be one or more, for example, all events monitored in a plurality of associated pages have unique identifications, for example, the identifications of different events in the same associated page are different, and the identifications of events in different associated pages are also different.
According to the embodiment of the invention, the monitored events in the associated page can be events which can change in response to the operation of the user, for example, the associated page is a news detail presentation page, wherein the monitored events can be, for example, the number of praise, the number of comment pieces, the comment content and the like. When the monitored event changes in response to the operation of the user, the associated page sends a notification of the change of the event, and the notification can be used for receiving and processing the associated page having an association relationship with the associated page. It is to be understood that the event in the embodiment of the present invention may be any event that may change, for example, the event may also be an event that changes according to a preset mechanism, and is not limited to an event that changes in response to an operation of a user.
In operation S220, the event in which the change occurs is recorded.
According to an embodiment of the present invention, the operation S220 may be, for example, storing an event identifier related to the received notification that the event has changed in a change list, so as to determine whether the event of the associated page subscription has changed in operation S230.
In operation S230, the subscription information of the associated page is called back, and in a case that it is determined that at least one event subscribed to the associated page changes, a notification that the at least one event changes is sent to the associated page.
According to the embodiment of the present invention, the associated page is a page having an association relationship with the associated page described in operation S210, that is, a part of the content of the associated page changes with the corresponding content of the associated page having an association relationship with the associated page.
According to the embodiment of the present invention, the subscription message of the associated page may specifically include an identifier of a subscription (listening) event of the associated page and a page identifier of the associated page (the page identifier may be represented by a subscribe Id, for example), and the subscription message of the associated page is called back, and the identifier of the subscription event is matched and compared with the identifier of the event recorded in operation S220, and when the event recorded in operation S220 includes the subscription event of the associated page, the notification that the event corresponding to the subscription event received in operation S210 changes may be sent to the corresponding associated page according to the page identifier of the associated page.
According to an embodiment of the present invention, the operation S230 may be specifically executed when the associated page is constructed, or may be executed in response to a request sent by the associated page, where the subscription information of the associated page may be specifically sent to the intermediary device in fig. 1 when the associated page is initialized, or may be sent when the associated page sends the request.
According to an embodiment of the present invention, in order to enable the intermediary device in fig. 1 to perform operations S210-S230 in fig. 2, the above associated page and associated page may be registered in advance in the intermediary device, and specifically, for example, when the intermediary device is initialized, a hash mapping table is created and a pair of keys is stored, where a key is used to store in advance an event source unique identifier (identifier of a subscribed event), and a value is a hash set of unique identifiers (page identifiers) of event subscribers (associated pages), so that the intermediary device may interact with the associated page and act as a basis for subsequently calling back subscription information of the associated page.
In summary, in the event processing method according to the embodiment of the present invention, when the associated page receives the notification that the event of the associated page changes, the associated page does not need to be maintained, and when the associated page sends the notification that the event changes, the associated page may not be established, that is, the associated page and the associated page may be decoupled, so as to implement the delayed notification of the event change, and thus the event processing method may be applied to more application scenarios.
Fig. 3 schematically shows a flow chart of an event processing method according to another embodiment of the present invention.
As shown in fig. 3, the event processing method of the present embodiment includes, in addition to operations S210 to S230 described with reference to fig. 2, operation S310, the operation S310 being performed before operation S220, and operation S220 may include operations S221 to S222 or may include operation S223 according to the determination result of operation S310.
According to the embodiment of the present invention, in operation S310, it is determined whether the event identifier hash set includes the identifier of the event, specifically, whether the event identifier hash set includes the identifier of the event that has changed in the notification received in operation S210. If not, it indicates that the associated page in operation S210 is initialized for the first time, or the event in the associated page in operation S210 changes for the first time, then operations S221-S222 are performed.
Storing the identification of the event into an event identification hash set in operation S221; in operation S222, a mapping relationship is established with the identifier of the event as a key and the empty hash set as a value. According to the embodiment of the present invention, the operations S221 to S222 may specifically be, for example, saving information of the event change in the hash map for the subsequent operation S230 to call the judgment.
As shown in fig. 3, the event processing method according to the embodiment of the present invention may further include, for example, operation S320 performed after operation S230.
In operation S320, the page identification of the associated page in operation S230 is written into a hash set of values whose keys are identifications of at least one event.
At least one event refers to an event that changes in the events of the associated page subscriptions mentioned in operation S230, specifically, is an event that is subscribed to by the associated page in the events having the mapping relationship established in operation S222. The page identifier of the associated page is specifically the page identifier in the subscription information recalled in operation S230, and the operation S320 is to write the page identifiers of the associated page into the values of the mapping relationship in operation S222, where the identifier of the at least one event is taken as a key, specifically, into the hash set in the mapping relationship.
In this way, when the associated page subsequently requests the notification of the event change, for example, it may be determined whether the value of the identifier of the event subscribed by the key for the associated page includes the page identifier of the associated page, and if the value of the identifier of the event subscribed by the key for the associated page includes the page identifier of the associated page, it is described that the associated page is notified of the event change, and there is no new change, at this time, the notification of the event change to the associated page in operation S230 may not be executed any more, and therefore, a defect that the notification needs to be repeated when the associated page is repeatedly constructed when the associated page is not changed may be avoided, and thus, resource waste may be reduced.
According to the embodiment of the present invention, in the case that the determination result in operation S310 is that the hash set of event identifications includes the identification of the event that has changed in the notification received in operation S210, it indicates that the event that has changed in the associated page in operation S210 does not occur for the first time, then operation S223 is performed.
In operation S223, in the case that the hash set of the key for the identified value of the event is not empty, the key is nulled for the identified value of the event and the empty hash set is reassigned. According to an embodiment of the present invention, this operation S223 may be specifically performed by, for example: first, it is determined whether a hash set of a value of the key that is the identifier of the event is empty, and if the hash set of the value is empty, it is known according to the scheme described in operation S320 that the notification of the event change has not been sent to any associated page, no processing is required; if the hash set of the value is not empty, the notification indicating that the event has changed is sent to some or all of the associated pages, the key is set to be empty for the value of the event identifier, and the empty hash set is newly assigned.
Through the execution of the operation S223, the embodiment of the present invention can ensure that when the notification that the event changes is sent to the associated page through the operation S230, the sent notification that the event changes latest is sent, and can avoid that the associated page corresponding to the page identifier written in the unmarked hash set cannot acquire the notification that the latest event changes.
FIG. 4 schematically illustrates a flow diagram of a method of sending a notification of a change in an event to an associated page, in accordance with an embodiment of the present invention.
According to the embodiment of the present invention, based on the event processing method described with reference to fig. 3, the operation S230 may specifically include, for example, operations S231 to S232.
In operation S231, subscription information of the associated page is called back, and the subscription information may include, in addition to the page identifier of the associated page, an identifier of an event of at least one associated page to which the associated page is subscribed. Specifically, as shown in the associated page 131 in fig. 1, the subscription information includes its own page identifier, and identifiers of change event 1, change event 4, and change event 5.
In operation S232, in case that at least one of the events of the associated page to which the associated page is subscribed is included in the event identification hash set, it is determined whether a page identification of the associated page is included in the hash set of values of which the key is an identification of the at least one event. Specifically, the operation may specifically include: first, it is determined whether the event identifier hash set includes identifiers of one or more events subscribed to the associated page, and if the event identifier hash set includes identifiers of some or all of the one or more events, it indicates that a notification that the some or all of the events are changed is received in operation S210, and the some or all of the events are changed; then determining whether the hash set of the key as the value of the identifier of the part or all of the events comprises the page identifier of the associated page, if the hash set of the key as the value of the identifier of the part or all of the events comprises the page identifier of the associated page, indicating that a notification that the part or all of the events are changed is sent to the associated page, and not executing any operation; if the key does not include the page identifier of the associated page in the hash set of the value of the identifier of the part or all of the events, it indicates that the notification that the part or all of the events have changed has not been sent to the associated page, and operation S233 is performed.
In operation S233, in a case where the key does not include the page identification of the associated page in the hash set of the value of the identification of the at least one event, a notification that the at least one event has changed is transmitted to the associated page.
According to the embodiment of the invention, in the event that the event identification hash set does not include the identifications of all events in the associated pages subscribed by the associated pages, the associated pages are not changed or not constructed, and then the associated pages are not processed.
In summary, in the embodiment of the present invention, the notification is sent to the associated page only when the event subscribed by the associated page changes and the notification that the subscribed event changes is not sent to the associated page yet, so that the event subscribed by the associated page is prevented from changing only once, and the associated page requests the same notification for multiple times, thereby effectively avoiding resource waste and improving the event processing efficiency.
As can be seen from the above, the event processing method according to the embodiment of the present invention can be implemented, for example, by referring to the intermediary device in fig. 1:
firstly, initializing the intermediary device, and creating an empty hash set during initialization, wherein the attribute of the empty hash set is that only non-repeating objects can be stored, and the empty hash set is specifically the preset event identification hash set; meanwhile, a hash mapping is also created during initialization for subsequent storage of key value pairs, namely for establishing the mapping relationship, wherein the key is unique, the identifier of the event is taken as the key, the value is a page identifier hash set of a subscriber of the event corresponding to the identifier of the event in the subscription key (namely, a page associated with the event is subscribed), and the initial value of the page identifier hash set is null;
secondly, when the event of the associated page changes, the intermediary device is informed of the identifier of the event to be changed, the intermediary device stores the identifier of the notified event into an event identifier hash set, stores the identifier of the event in a hash map as a key, and gives the key an empty hash set as a value, wherein if the mapping relation which takes the identifier of the event as the key already exists in the hash map and the hash set of the value of the key is not empty, the hash set is emptied to newly add a new empty hash set;
then, when a notification of event change is requested under the condition of associated page construction/reconstruction, or a periodic notification of event change is requested, request information is sent to the intermediary device, and the intermediary device firstly judges whether the event identifier hash set contains the identifier eventId of the event subscribed by the associated page when receiving the request information, and if not, the event source does not exist, and the processing is not performed; if yes, checking a hash set of the value of the identifier of the event of which the key is the associated page subscription, judging whether the hash set contains the page identifier subscriber Id of the associated page, and if yes, indicating that the associated page consumes the subscribed event, not performing subsequent processing; if yes, executing the subsequent flow;
and finally, responding to the request of the associated page, carrying out callback processing of the event change of the associated page, sending a notification that the subscribed event changes to the associated page, and storing the page identifier of the associated page in a hash set of which the key is the value of the identifier of the subscribed event, so that the associated page successfully consumes the event change.
Fig. 5 schematically shows a flow chart of an event processing method according to a further embodiment of the present invention.
As shown in fig. 5, the event processing method according to the embodiment of the present invention includes operations S510 and S520 in addition to operations S210 to S230.
According to an embodiment of the present invention, the event processing method according to an embodiment of the present invention may further include operations S310 to S320 described with reference to fig. 3, where the operation S220 specifically may include, for example, operations S221 to S222 described with reference to fig. 3, or may include operation S223 described with reference to fig. 3, and the operation S230 may include operations S231 to S233 described with reference to fig. 4.
In operation S510, unsubscribe information of the associated page is recalled. Specifically, for example, the unsubscribe information may be that the associated page is sent to the intermediary apparatus in fig. 1, and then the operation S510 is executed when the intermediary apparatus receives the unsubscribe information of the associated page. Wherein the unsubscribing information comprises: the identifier of the event of at least one associated page subscribed by the corresponding associated page, and the page identifier of the corresponding associated page. And the corresponding associated page is the page for sending the unsubscribe information.
In operation S520, in the case that the hash set of the value of the identifier of the event of the at least one associated page to which the key is subscribed for the associated page includes the page identifier of the corresponding associated page in the unsubscribe information, the page identifier of the corresponding associated page in the unsubscribe information is removed.
In summary, when the associated page does not need to monitor the change of the event of the associated page any more (specifically, for example, when the content of the associated page is modified and does not have an association relationship with the associated page any more), the intermediary device deletes the relevant information of the associated page in time by calling back the unsubscribe information, so that the occupied space of the memory can be reduced to a certain extent, and the event processing efficiency can be improved in time.
According to the embodiment of the present invention, in the case that the associated page no longer needs to monitor the change of the event of the associated page, for example, the association relationship between the associated page and the associated page may be cancelled through an additionally set association relationship cancellation logic, specifically, for example, when the associated page sends unsubscribe information, the registration information of the associated page may be deleted according to the additionally set association relationship cancellation logic, specifically, for example, the page identifier of the associated page recorded in the hash set may be uniquely identified in the hash mapping table created when the broker apparatus is initialized. It is to be understood that the above-described association cancellation logic is provided as an example only to facilitate understanding of the present disclosure, and the present disclosure is not limited thereto.
According to an embodiment of the present invention, the event processing method described above with reference to fig. 2 to 5 may be specifically implemented by, for example, a singleton mode to ensure global uniqueness, and in order to ensure security of singleton threads, a double check lock may be further added in the singleton mode. Specifically, when the event processing method described with reference to fig. 2 to 5 is performed by the mediation device described with reference to fig. 1, the mediation device may be created through the singleton schema, and a double check lock is added when the mediation device is created, so as to effectively prevent the singleton class from having multiple instances.
