Description
Technical field
The present invention relates to one kind to be related to Programming pattern field, the application of multimode, primary structure (non-container injection)
Program development, most widely used is flash web games, more particularly to a kind of module communication means for supporting message mechanism.
Background technology
In the medium-and-large-sized application of any language structure, there are many modules, how to allow these modules to communicate to each other,
Need to think thinking and design architecture, to meet good autgmentability.Here cast aside as javaEE etc. is with container injection
Server architecture, discussion is the framework voluntarily realized based on flash.Flash can regard a pure front end as in itself
(V) when, but it is as an operation simultaneously, inside can also include structure and the processing of controller (C) and data model (M).
As many large, medium and small web games, all gone to build whole performance with flash.In one flash application, several moulds are included
Block.Such as web game, toward big point, there are mapping module, role module, task module, knapsack module, store module, fight mould
Block, good friend's module, module etc. of forming a team；It is divided into several submodules again under each big module, under role module, includes male
Player, women player, NPC etc..Between these modules, may all there is contact.Appoint as male's player's cutting falls a band
When the BOSS of business, it is notified that task module completes a task, while be also notified that broadcast system is wide to full server
Cutting boss is broadcast, may can also be broadcasted to good friend and obtain what superfine product equipment, bound new achievement to achievement system, support or oppose
Article that packet system renewal newly harvests etc..That is, an event, several other events may be triggered, and these
Event is dispersed in different modules.Way before very early is to use " singleton pattern+combination ", and which module needs to change,
Just directly invoke the method under the module.Such degree of coupling is very high, it is easy to malfunctions, and to extending and safeguarding pole not side
Just.
In Windows systems, program is event driven, all IO inputs all Windows monitoring, when an event
During generation, the message of input is first put into system message queue by Windows, then again by the message copying of input to accordingly
In application queue, the message loop in application program retrieves each information and sending to corresponding from its message queue
Window function in carry out event processing.In flash, flash also has case mechanism (Event), and event machine in itself
It is formed with the flow of event of complete set.But the case mechanism requires that the listener of event must inherit IEventDispatcher and connect
Mouthful；The self-defined controllability of event is not strong, for example is unable to hook；In registered events, coupling still can occur (such as using group
Close to declare member variable or singleton).
The content of the invention
The purpose of the present invention is that providing one kind solves the above problems, the local message communication mechanism based on flash
Support the module communication means of message mechanism.
To achieve these goals, the technical solution adopted by the present invention is：A kind of module communication party for supporting message mechanism
Method, it is characterised in that：Method and step is as follows,
Step 1: a Message dictionary MsgID is created, for preserving the ID of all self-defined messages；
Step 2: creating the base class BaseMsg of a message, remaining any self-defined message inherits the base class；
Step 3: create a message manager MsgManager, be responsible for the monitoring of message, transmission, execution, nullify it is interior
Section mechanism is realized；
Step 4: creating a self-defined message msg1, BaseMsg is inherited, has a message id in the message：MsgID,
It is tied in an ID in MsgID, sets object A as message sending object, object B is message sink object (listener),
Fun () method is the specific monitor method of message, and the message of the message is registered in message sink object B initial method
Monitor, binding execution method fun (), it is necessary to send the place of message in message sending object A, pass through post or send side
Formula sends message m sg1, and so after A has sent message, the method monitored in B will be performed immediately.Send message side
Method is as follows, and the message that the message is registered in the initial method in B is monitored, and passes through MsgManager.registerMsg
(msgID, fun), binding execution method fun ()；Object B fun () place is called in object A, is entrusted
It is MsgManager.postMsg (msg1) or MsgManager.sendMsg that MsgManager, which sends the message m sg1, msg1,
(msg1)。
Preferably, this method is the framework voluntarily realized based on flash, Flash regards a pure front end as in itself
(V) when, but it is as an operation simultaneously, inside can also include structure and the processing of controller (C) and data model (M),
This patent is to be based on flash, but thought can be used for any language.
Preferably, in step 4, created in message manager MsgManager a message queue (such as：Number
Group Array types), the message sended over for caching post, to perform asynchronous process.
Preferably, in step 4, registerMsg methods, this method are created in message manager MsgManager
Receive and be responsible for receiving two msgID, message call back function parameters, array, call back function deposit number are created using msgID as key
Group (i.e. observer), so as to which all observers when receiving the message that send or post come, can be broadcast to, perform all disappear
Breath readjustment.
Preferably, in step 4, in message manager MsgManager, postMsg methods and sendMsg side are created
Method, the two methods are used to send message, and post is that delay is called (i.e. asynchronous execution message is adjusted back) after sending, and send is to send
Call (i.e. synchronous to perform) immediately afterwards, two methods all receive a parameter msg, i.e. BaseMsg subclass object, pass through send
The message to come over, can take out the msgID of msg objects, travel through and find from message queue, find out corresponding to the message id and own
Observer, the message readjustment of these observers is performed immediately after, the message to be come by post, will not be immediately performed, but
First it is put into another message and performs queue, then passage time piece asynchronous execution.
Preferably, the message sended over by post, is placed in message queue, timing is gone by a timer
Check, once it is not sky to detect queue, just take out (shift) message from queue to perform by intervals；And lead to
The message that send is sended over is crossed, is not put into message queue, but be immediately performed.
Preferably, in step 4, message manager MsgManager processing message circulates, and is monitored in message sink object
Returned to message, perform method fun ().
Preferably, in step 3, Observer Pattern that message manager mainly uses sees message distribution to corresponding
On the person of examining, last listener performs corresponding method；Message can be by hook, hook Message Listener elder generation registration message simultaneously
Hook is monitored, and sender of the message retransmits message, and message manager intercepts message, by message distribution according to hook messaging list
Seen to corresponding on hook, last hook performs corresponding hook methods.
Compared with prior art, the advantage of the invention is that：The present invention allows module on the basis of good communication, beneficial to expansion
Exhibition and maintenance, so as to make system more healthy and stronger.(the container injection that many frameworks provide being cast aside, just for primary exploitation) traditional mould
Communication between block, otherwise it is at a relatively high using the method for combination, directly tune object, such degree of coupling；Using language in itself from
The case mechanism of band, so with certain limitation.By introducing local message communication mechanism, make module decoupled, beneficial to mould
The extension of block can just solve the above problems well., developer develop multimode application when can experience the convenient of the program.
Brief description of the drawings
Fig. 1 is normal messages schematic flow sheet；
Fig. 2 is the message flow schematic diagram with hook mechanism.
Embodiment
The invention will be further described below.
Embodiment 1：A kind of module communication means for supporting message mechanism of the present invention, is performed in local message communication mechanism,
So-called local is exactly message without network, only using internal circulation；So-called " message communicating ", exactly send, receive and disappear
Breath.Be somewhat like http communication send, post, only overall process inside application without walking network.Also it is somewhat like in js
Event, be divided into action listener person, Event senders, event executor, only with event handling or different.The present invention's
The means of communication, the communication of all intermodules can be regarded as " local message " one by one, there is a message manager and one
Messaging list, the registration of message manager management message are monitored, send, received；Messaging list manages unique ID of every message.
The place of transmission message is being needed, message manager is being allowed to act on behalf of and sends message (send and post)；Needing received message
Place, message manager agency is allowed to carry out received message (first registering regist).The sender and recipient of message do not recognize mutually, hair
That send sends by all means, and reception receives by all means, to reach full decoupled.The observer that message manager mainly uses
Pattern.Meanwhile message can be by hook, to solve some sudden work.
Normal message flow, referring to Fig. 1, message manager is with Observer Pattern structure message system；Listener is first
Registration message is monitored, and sender of the message retransmits message；Manager is responsible for, by message distribution to corresponding observer, finally supervising
Hearer performs corresponding method, and whole information communication mechanism has 5 roles：Message manager, message id dictionary, message, message
Sender, message recipient (also referred to as listener)." fun () method that object A calls object B " is called according to traditional combination,
It is put into message mechanism, then object A is exactly the sender of message, and object B is exactly recipient's (listener) of message, fun
() method is exactly the specific monitor method of message.
A kind of module communication means for supporting message mechanism, specific method step is as follows,
First, Message dictionary MsgID, then create the base class BaseMsg and a message of a message one by one is created
Manager MsgManager.In MsgID, the ID of all message is preserved.Each customized message inherits BaseMsg, simultaneously
An ID is bound in MsgID.In MsgManager, it is responsible for monitoring, transmission, execution, the internal mechanism realization nullified of message.
Secondly, a self-defined message msg1 is created, inherits BaseMsg；The message prison of the message is registered in initial method in B
Listen (by MsgManager.registerMsg (msgID, fun)), binding execution method fun ()；B.fun is called in A
The place of (), commission MsgManager send message m sg1 (MsgManager.postMsg (msg1), or
MsgManager.sendMsg(msg1)).So, after A has sent message, the method monitored in B will be performed.It is above-mentioned
The post and send talked about, it is the modes of two kinds of transmission message, different from the post and send in http agreements, here
Post is to postpone to call after sending, and send is called immediately after sending, and specific implementation is in MsgManager, is sent out by post
The message brought, is placed in message queue, and regular check is gone by a timer, once it is not sky to detect queue, just
(shift) message is taken out to perform from queue by intervals；And the message sended over by send, it is not put into and disappears
Queue is ceased, but is immediately performed
Created in message manager MsgManager message queue (such as：Array Array types), for caching
The message that post is sended over, to perform asynchronous process.
The establishment registerMsg methods in message manager MsgManager, the responsible reception msgID of this method reception,
Two parameters of message call back function, using msgID as key create array, call back function deposit array (i.e. observer), so as to
When receiving the message that send or post come, all observers can be broadcast to, perform all message readjustments.
In message manager MsgManager, create postMsg methods and sendMsg methods, the two methods are used for
Message is sent, post is to postpone to call (i.e. asynchronous execution message is adjusted back) after sending, and send is called immediately (i.e. synchronously after sending
Perform), two methods all receive a parameter msg, i.e. BaseMsg subclass object, the message to be come by send, can incite somebody to action
The msgID of msg objects takes out, and travels through and finds from message queue, finds out all observers corresponding to the message id, immediately after
The message readjustment of these observers is performed, the message to be come by post, will not be immediately performed, but be first put into another message
Queue is performed, then passage time piece asynchronous execution.
Message manager MsgManager processing message is circulated, and message return, the side of execution are listened in message sink object
Method fun ().
The Observer Pattern that message manager mainly uses, by message distribution to corresponding observer, last listener
Perform corresponding method；Message can be by hook, the message flow with hook mechanism simultaneously, and referring to Fig. 2, hook message is monitored
Person elder generation registration message hook is monitored, and sender of the message retransmits message, and message manager disappears according to hook messaging list, interception
Breath, message distribution is seen on hook to corresponding, last hook performs corresponding hook methods.
And the local message communication mechanism of this programme, do not require that the listener of message realizes any interface or inherits any class
Type, but entrust to message manager to go to monitor；The manual hook of energy, truncated message do other things；Complete decoupled, the hair of message
The person of sending and recipient only come into contacts with message manager respectively, do not know the presence of other side mutually.Message in this programme is led to
Letter mechanism, (and and non-substituted) can be combined with many frameworks, such as MVC；Simultaneously can also be complete with case mechanism that language carries
U.S.'s fusion (also and non-substituted).
Exhaustive presentation is carried out to a kind of module communication means for supporting message mechanism provided by the present invention above, herein
In apply specific case to the present invention principle and embodiment be set forth, the explanation of above example is only intended to help
Assistant solves the method and its core concept of the present invention；Meanwhile for those of ordinary skill in the art, the think of according to the present invention
