Detailed Description
Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
Referring to fig. 1, an embodiment of the present invention provides a search list updating method, including the following steps:
creating an aggregation list, wherein the aggregation list is used for recording the equipment information in the current local area network and sequencing the equipment information of the aggregation list according to a preset priority;
creating a device adding and deleting function used for adding and deleting the device information in the set list; at the same time, the user can select the desired position,
when the device adding and deleting functions are executed, the set list stops sequencing, and after the device adding and deleting functions are executed, the set list is reordered.
The aggregation list is used for recording and sequencing the equipment information in the current local area network, and the sequencing order of the equipment information is according to the preset priority;
the equipment adding and deleting function is used for adding and deleting the equipment information in the set list so as to update the equipment information in the set list;
the priority of each piece of equipment information in the set list is different, the set list needs to be sorted again after being updated, when the equipment adding and deleting functions are executed, the set list stops sorting, and after the equipment adding and deleting functions are executed, the set list is reordered, so that the phenomenon that the equipment information in the set list is added and deleted at the moment to cause the abnormal condition that the array in the set list is out of bounds when the set list is in the sorting process can be avoided.
When the set list sorts the equipment information, the stop and the start of the sorting work can be controlled according to the execution condition of the adding and deleting functions of the equipment, and the stability of data processing is improved.
The invention can dynamically update the search list without influencing the execution state of the whole application program, thereby improving the stability of the program.
In this embodiment, the method for updating the search list further includes the following steps:
creating a monitoring variable, wherein the monitoring variable is used for indicating whether the equipment add-delete function is in an executing state or not;
by monitoring the variable, the execution state of the equipment adding and deleting function can be known, and different values of the monitoring variable represent whether the equipment adding and deleting function is in the executing state or not;
specifically, the initial value of the monitoring variable is false, when the device add/delete function starts to execute, the value of the monitoring variable is changed to true, and after a set waiting time, the value of the monitoring variable is restored to false;
when the value of the monitoring variable is true, stopping sequencing of the set list, and when the value of the monitoring variable is changed from true to false, restarting sequencing of the set list;
the latency may be 100 milliseconds;
the monitoring variable can be a global boolean variable isHandling, the isHandling is initialized to false, the value of the isHandling is set to true each time the add-drop function is executed, and the value of the isHandling is set to false after a delay of 100 milliseconds after the add-drop function is executed;
it should be noted that the reason why the waiting time is set to 100 ms is to avoid that the sorting logic does not react yet due to the fast switching speed of the isHandling value, thereby causing an exception to the sorting logic;
the monitoring variable can restore the self value to the initial value, and convenience is provided for the next search list updating work.
In the embodiment, when the aggregation list receives a plurality of calling equipment add-delete function requests, the calling equipment add-delete function requests are subjected to time sequencing, and the aggregation list operates in sequence according to the time sequencing;
the technical scheme is mainly used for extremely extreme cases, namely the interval time between the arrival of data added and deleted by one device and the arrival of data added and deleted by the next device is short and shorter than the execution time of an adding and deleting function, or when an aggregation list is subjected to multi-thread operation, the aggregation list is automatically queued, when the processing of a first thread is completed, a second thread is arranged again for processing, namely a series of requests are cached, and then the requests are processed in sequence, so that the problem is avoided in the extreme cases, and the maintenance of the whole data can be free from any abnormality.
In this embodiment, the method for updating the search list further includes the following steps:
after the execution of the adding and deleting functions of the equipment is finished and the equipment information in the collection list is ordered and updated, UI (user interface) updating of the collection list is carried out;
in order to solve the problem in the traditional scheme, the add-delete callback function only performs cache operation on data, the add-delete process of the device is not embodied on the UI, and the UI of the collection list is updated only after the device information in the collection list is sequenced and updated; because only the addition and deletion of the equipment information do not involve any UI operation, the time-consuming operation in the whole operation process can be almost ignored, and the flow of the processing process is ensured.
It should be noted that the device add/delete function includes a device add function and a device delete function, where the device add function adds device information in the aggregation list, and the device delete function deletes device information in the aggregation list.

the equipment adding and deleting unit is internally provided with an equipment adding and deleting function, and the equipment adding and deleting function is used for adding and deleting the equipment information in the collection list;
when the device adding and deleting functions are executed, the set list stops sequencing, and after the device adding and deleting functions are executed, the set list is reordered.
In this embodiment, the search list updating system further includes:
the monitoring unit is internally provided with a monitoring variable, and the monitoring variable is used for indicating whether the equipment adding and deleting function is in an executing state or not;
specifically, the initial value of the monitoring variable is false, when the device add/delete function starts to execute, the value of the monitoring variable is changed to true, and after a set waiting time, the value of the monitoring variable is restored to false;
when the value of the monitoring variable is true, stopping sequencing of the set list, and when the value of the monitoring variable is changed from true to false, restarting sequencing of the set list;
the latency may be 100 milliseconds.

and when the aggregation list receives the multiple calling equipment add-delete function requests, time sequencing is carried out on the multiple calling equipment add-delete function requests, and the aggregation list is sequentially operated according to the time sequencing.
In this embodiment, in the search list updating system, after the device add/delete function is executed and the device information in the aggregation list is ordered and updated, the UI of the aggregation list is updated
It should be noted that: in the system provided in the foregoing embodiment, when the dynamic update operation of the search list is implemented, only the division of the functional modules is illustrated, and in practical application, the function distribution may be completed by different functional modules according to needs, that is, the internal structure of the system is divided into different functional modules, so as to complete all or part of the functions described above.
