Component reverse calling platform and method for inter-component similar group communication

Abstract

The invention discloses a component reverse calling platform and a method for inter-component similar group communication. The component can reversely call the functions of the platform or component in the platform through a regional development agency RDA by the steps that: a component calls a COM object in the platform by a COM interface intelligent pointer provided by the platform; and the COM object calls the functions of the platform or component in the platform by functional mapping. The method for the inter-component similar group communication comprises the following steps that: the component sending the data sends the data to a communication agency; an event connecting point in the RDA responds to a calling-back service of the communication agency; and a monitor in the component monitors the event connecting point and acquires the data in the calling-back service. The system based on the method comprises a COM calling module, a COM object module, a function agency module, a communication agency module, a communication agency calling-back service module and an event monitoring module. The component reverse calling platform of the invention can improve development efficiency and lower operating cost of the system; and the similar group communication can lower the network traffic of the 'platform and component' system during the inter-component communication.

Description

technical field [0001] The invention relates to the technical field of software architecture based on "platform + component", and in particular to a method in which a component can reversely call a platform and perform "like multicast" communication between components. Background technique [0002] The software architecture of "platform + component" is an organic combination of "platform"-based development and "component"-based development of CBD. In this system architecture, the "platform" usually integrates the common basic functions of the system and provides a unified integration framework; while the "component" provides certain specific or professional functions. The "component" is integrated into the "platform" through the unified integration framework provided by the "platform", and forms an overall application system together with the "platform". This traditional "platform + component" system architecture can be used figure 1 to illustrate. [0003] In this tradit...

AI Technical Summary

Problems solved by technology

Although this "contract" method can solve certain problems, the "contract" agreement is often difficult and the efficiency is very low (for example, the efficiency of database access and file reading is relatively low, and the polling mechanism sometimes has a large overhead on system resources. )

Therefore, in general, because the platform does not provide a secondary development function interface, the scalability of the system is relatively poor

[0008] In the second mode, the platform provides a secondary development function interface, which overcomes the shortcomings of the first mode to some extent, but the problem is that there is no unified integration framework and system operation mode, so the developed system There are serious deficiencies in integration, interoperability, scalability, use style and interface standardization, and maintainability.

Although the platform can be started and shut down manually, since it is difficult for us to determine when the system needs platform services, it is best to keep the platform running all the time)

[0009] In addition, there is another situation where the above two modes are powerless, that is, multiple components of a system need to receive a message or data from an external system (or other systems or components on other network nodes) at the same time
