Description

Realize the synthesis interface that theme is linked up

Technical field

The present invention relates to the instant communication message technology field under computer application environment, more particularly to system application process In by system message model, component model and messaging protocol, information or task are transmitted between multi-user With execution.

Background technology

Theme is linked up, and concept originates from the instant communication message technology field under computer application environment, is for daily The concept that there is fixed routine activity in work and propose, it is therefore an objective to realize that user is realized from each other by comprehensive interface Theme link up, reach and improve operating efficiency, more preferable control process, enhancing to the servicing of client, effective management business flow The purpose of.Theme ditch Tonghua needs first to extract substantial amounts of message content (even text picture) simultaneously from user's request Work is sorted out, and is that time-consuming may not can also meet the need that user's request is changed repeatedly the step for for periodic project Will.The message content of supplement can also be added to by way of extension during system development later stage or maintenance, upgrading Come, but this needs also exist for system and a variety of parameters in later stage are just considered in the design phase and reserve the interface of extension.And for The higher system of requirement of real-time, for example manufacture industry management software and use theme ditch Tonghua equally also improper.It is because main Substantial amounts of message content (text even picture) is spread through the internet in the implementation process of topic ditch Tonghua, expense therebetween is not It can neglect.Various problems are inevitably produced when being applied in the high system of real-time.

Theme ditch Tonghua technology recommends you as needed to put message content in position, the demand of each system and Implementation has more or less difference, and the position for depositing message content directly influences the overall performance of system, therefore must It can only also must be weighed according to the characteristics of oneself.Theme ditch Tonghua represents will there is message in somewhere in internal memory, can be this Heap message, which is placed on service end, can also be placed on client.For the former, client, which needs frequently to send to service end, asks, and obtains Take required message content；For the latter, client will be also responsible for except all message contents are moved to local from service end State and validity that theme is linked up are safeguarded, perhaps it is also contemplated that the problems such as synchronous.We model field to current process The main flow modeling method occurred has carried out reductive analysis, can be divided into 5 major classes：Script, the method based on net, The method and algebraic method of method, logic-based based on more loose-leaves.(1) controlling stream and data flow are described in script Sentence structure, it provides a kind of concise description method, is easier to use for experienced designer.It main Shortcoming is a lack of the Formal Semantic of flow in itself, and the semanteme of language mainly uses for language interpreter.(2) side based on net Method is suitable for the visual modeling of flow, and typically all use state transition net, the activity in flow represent that controlling stream is used with node Side represents.The subject matter of use state transition net be whether the semanteme of tangible formula, most of working flow products it is visual Change modeling method and all lack Formal Semantic.In the status change net with Formal Semantic, make with the most use be exactly Petr nets and state diagram.(3) method based on more loose-leaves, the current most studied method based on more loose-leaves are ECA more living Page.The more loose-leaves of ECA have formalization basis, but the visual work amount of the more loose-leaves of ECA is bigger, if more loose-leaf collection compare Just it is difficult to manage when big.(4) method of logic-based is suitable for the dynamic of description system, and wherein sequential logic is a kind of conventional Method, it have well formalization basis, verify that the attribute of Work flow model is more convenient.But sequential logic is main Shortcoming is that visualization difficult to realize is not easy to be converted into other description methods, and the system action for describing operation flow is too complicated. (5) method based on algebraically is mainly still confined in theoretic discussion, uses seldom in Workflow Management field, only a kind of base It is used for Workflow Management field in the description language LOTOS of process algebra.The major defect of algebraic method, which is similar to, to be based on patrolling Volume method, and it is automatic perform and Formal Verification in terms of show must be more worse than the method for logic-based, modeling method lacks Weary intuitive, it is difficult to understand.

System realizes benefit caused by the synthesis interface of theme communication：Realize the side of synthesis interface one that theme is linked up Face provides flexible, convenient operation interface for system manager, on the other hand can realize the synchronous exchange of data and share Feature it is more popular with users, effectively help system can simplify unnecessary flow, be the direction of future work Flow Technique development.

The content of the invention

In order to overcome the shortcomings of the existing synthesis interface realized theme and linked up, the present invention provides one kind and realizes that theme is linked up Synthesis interface, component is independent computing module, can be write with any language.Communication between component is still to pass through What message transmission was completed, message is transmitted between users.Each component has the message pool of a carry, and message pool is message Carrier, on the one hand it is used for the result of calculation for storing local component, is on the other hand used to receive the message from other components.It is a kind of Uniformly realize that message pool model, component model and messaging protocol scheme, messaging protocol define structure in application layer Message access rule between part, the messaging protocol of the selection gist static state of message path.In system stable operation In the case of, the content of the message transmission between component and direction are fixed, therefore are not necessarily to the dynamic in system operation Ground carries out message route.

The technical solution adopted for the present invention to solve the technical problems is：Realize the synthesis interface of theme communication in usual feelings Output themes link up the state change information for being responsible for receiving member under condition.If there occurs state change in the process of running for component Change, then the status data of component links up unloading in theme, waits other components to take；It is responsible that other side takes complete rear theme to link up The message is destroyed, and reclaims internal memory, to receive new message.If the message is used in a number of other components, then theme Link up after all demand components all take and finished and destroyed again.Input themes, which are linked up, is responsible for the message for receiving other components simultaneously Notification component message oneself through reach.Component can select to handle at once or postponement processing, if selection postponement processing, theme ditch Logical to preserve this message always for component, theme ditch generalist reclaims the message space after being disposed.

The invention has the advantages that realizing the synthesis interface that theme is linked up, reduce message in the direct transmission of message Assignment and filter action.The registration and transmission of message are recorded in the messaging protocol concluded in advance.Messaging protocol Exactly the transmission management of message is stripped out from bus functionality, substantially reduces calculating time during system operation, or use Static agreement exchanges dynamic routing procedure for；Another aspect message transmission and the service logic of component, which calculate, to be separated, and is reduced The complexity of system design.

Embodiment

In fig. 2, the synthesis interfacial structure figure for realizing that theme is linked up is illustrated.All message contents are placed on resource text In part (Resource), resource file can be compiled and embedded in (.net) in procedure set dll.Deposit the resource text of message content Part is placed on server end, by client request and obtains.

1. during client is from service end request service, service end is passive and stateless, its responsibility Whole message contents is exactly read from resource file, and client is sent to by network by suitable carrier, by visitor Family terminates by and handled.Application for Internet, using XML Web Servervice technologies, pass through XML sequence Change and soap protocol solves the puzzlement of fire wall.Use List<string>The message content carrying of text type is got up, it Both support Binary Serialization or support XML serialization, it is very convenient.

2. client after service end is asked and gets message flow, locally will make message caching.This process is also Need to simply it handle, because the messaging list that service end sends over does not have clearly classification, also inconvenient local basis disappears Cease the specific message content of name index, that is to say, that also to realize according to " this name of message A " find message A content this The effect of sample.Using hashing mode, Dictionary as key-value pair<string,string>(Dictionary in .net The general stencilling sheet of data type) three class key-value pairs of structure, including error message set Errors, warning message set Warnings, general information set Informations.These information aggregates are regarded as global object and are cached in internal memory always In, they have collectively constituted a message pool, and the Form or web interface to foreground provide informed source, until client is closed.
