Problems solved by technology

The C++ constructor is an ordinary function, so it cannot be executed remotely, and it has no return value, so when the construction fails, it will be extremely difficult to know the cause of the failure. For components that require remote construction, the construction fails It is a common phenomenon that the client needs to understand the cause of the failure in order to deal with it accordingly, but the traditional C++ construction process and mechanism cannot meet such requirements, thus limiting the further development of component technology in distributed systems

Embodiment Construction

[0030] In order to understand the technical content of the present invention more clearly, the following examples are given in detail.

[0031] see figure 1 As shown, the construction method in the component initialization process includes a server and a client connected through a computer network, wherein the method includes the following steps:

[0032] (1) The system performs initialization operation;

[0033] (2) The system adds component interface description information and a specific constructor to the component description file according to user operations. The format of the specific constructor is: constructor identifier ([input] input parameter), where the constructor identifier can be As a constructor, of course, other identification strings can also be used according to the habits of programming developers;

[0034] (3) The system reads the component description file, generates metadata, and generates a construction interface class code framework including constr...

Abstract

The invention relates to a construction method in constructing initialization process. It includes the following steps: adding component interface unit data, special constructing function to component expression file; generating construction code frame according to special constructing function; generating construction calling method, component object species factory at client end according to component interface unit data; and acquiring corresponding construction interface species; calling corresponding construction interface method and return the operation result. The method could realize component remote constructing method and support distribution system. It improves developing efficiency and execution efficiency, lowers developing difficult, enhances stability, etc.

Description

technical field [0001] The invention relates to the technical field of computer software, in particular to the field of computer componentized software systems, and specifically refers to a construction method in the process of component initialization. Background technique [0002] With the further development of modern component-based computer software technology, CAR (Component Assembly Runtime) component technology is a technology that uses component-oriented programming (Component Oriented Programming, referred to as COP), which defines a set of component programming models and The programming specification stipulates a set of standards for calling each other between components, so that binary components can describe themselves and be dynamically linked at runtime. [0003] At present, CAR component technology has been implemented on some advanced embedded operating systems, and users can easily write their own components under the SDK (Software Development Kit) of the ...
