Embodiment
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Consult Fig. 2, the main flow chart of the method for the invention, middleware at first judge whether the message that event occurs, if having, then incident generation module identifies message, one of type of message and code unique identification or the specific message of a class.Message and the message identifier corresponding with it that the module of incident generation afterwards will send are packed together, and the message of packing is sent to message and unifies processing module.
It is reception, classification, management, coordination and the distribution of carrying out message that message unifies that processing module mainly acts on.A message has two attributes: type and code, type are meant the source of message, and code is meant the feature of message.Message is unified processing module and mainly contained following function: 1. registration/logout message is adjusted back; 2. message sends and broadcasting; 3. Message Processing is promptly carried out the overall coordination processing by the priority of message.
Each will receive, at first to want the registered callbacks function be message to row to the thread of processing messages.The effect of registration is to unify the whole message of processing module to new information node of interpolation in being listed as to message, this node is to have set up a corresponding relation between type of message and message code and call back function, by this corresponding relation, message processing module can be distributed to message in the formation of each information node easily.After this message queue was used for message and is distributed to this formation, message had a buffering under the untimely situation handling.
Nullify readjustment, message is unified processing module and is identified in the message queue according to readjustment and searches for, search the node of coupling after, this node is deleted from message queue.
After message is unified processing module and is received message, resolve according to message identifier, determine its priority, and message is distributed in the different message queues according to priority.
Fig. 3 is the message parse process chart, the dissection process concrete steps are: judge whether present node is last node of message queue, if not judging further then whether current thread ident value and message parameter mate with the value of present node, whether the message queue of present node is empty, if the coupling and be the sky, then the call back function that the value of first message of the messaging list of present node is passed to present node, and return the type of this message, otherwise carry out next node, if present node is last node of message queue, then return error code and end.
Need send or incident when taking place as data, the module that sends message has dual mode to send message to the message management module: send to the receiver module in the specific thread 1.; 2. be broadcast to the receiver module of all threads.
The point-to-point transmission process chart that Fig. 4 sends for message, the message that sends to particular thread according to message except that carrying type of message and message code, also include the information of subject thread, after the message management module obtains this message, this message is distributed to given thread.Its concrete steps are: judge whether present node is last node of message queue, if not judging further then whether whether input parameter thread identification value and message parameter surpass restriction with the value coupling of present node, the message count of present node, if coupling and surpass restriction then the message parameter of input is added in the message queue of present node, return and send successful information and end, otherwise carry out next node, if present node is last node of message queue, then return error code and end.Therefore, have only this thread can receive this message, other threads can not obtain this message.So both guarantee the efficient that message is transmitted, guaranteed security of system again.
Broadcast is meant this incident and sends data issues all modules of system, and the module in any thread need be used all registrable this message of this message and obtain the message of the type and code.
Fig. 5 sends process chart for information broadcast.Broadcast transmission comprises the steps: to judge whether present node is last node of message queue, if not judging further then whether whether the input message parameter surpass restriction with the value coupling of present node, the message count of present node, if coupling and surpass restriction then the message parameter of input is added in the message queue of present node, otherwise carry out next node, if present node is last node of message queue then finishes.This makes some message send a plurality of modules in back all can get access to this message when need use this message in the message management module, also be broadcast to receiver module for this event information that once sends a plurality of receptions in mode the most efficiently.
Then, receiver module is inquired about registered message queue, as formation message is arranged, and then takes out message according to first in first out, calls call back function and handles this message, handles back this message of deletion from formation.
Message Processing is divided into two parts: one is the distribution processor that the message management module is carried out according to different modes and different priorities message; Another is to the information that the message transmission the comes processing of classifying, and after being used to complete this message is deleted from the formation of message management module.
It mainly is the high first allocation process of carrying out of priority to be realized the operation of the total message of system is guaranteed by the point-to-point transmission of thread, point-to-area broadcasting with according to priority by message that message unifies that processing module handles message unified.This message mechanism adopts the processing of message data is carried out at receiving thread respectively, to guarantee the efficient of message management module to message response, can not cause overstocking of message.The Message Processing of second portion is exactly that finger is received the processing procedure of the interface of module invokes message processing module to message.Message is unified processing module according to the formation of current thread ident value search message, search the node of coupling after, first message of the messaging list that this node comprised is passed to call back function handles.
At last, judge whether message queue is empty, not empty parsing, distribution and the processing messages of then continuing, otherwise finish.
Unify in the processing method in digital television receiver middleware message of the present invention, between middleware layer or intermodule adopt unified message passing mechanism, each layer or inside modules can have the message event mechanism of oneself, also can utilize this total message mechanism to realize inner message transmission.
Digital television receiver middleware message of the present invention is unified processing method, mainly is responsible for the message transmission and the event response of following several levels: 1. message transmission between application layer and middleware layer; 2. message transmission between the middleware module inside; 3. message transmission between bottom layer driving and the middleware layer.The present invention has the entire system allotment and the coordination ability, different according to the real-time of message and priority, and message processing module carries out Coordination Treatment to all message of system, has guaranteed the stable of system, has improved the overall operation efficiency of system.
It should be noted last that: above embodiment is the unrestricted technical scheme of the present invention in order to explanation only, although the present invention is had been described in detail with reference to the foregoing description, those of ordinary skill in the art is to be understood that: still can make amendment or be equal to replacement the present invention, for any modification or partial replacement that does not break away from the spirit and scope of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
