Problems solved by technology

The C / C++ language itself does not have this feature, so it is impossible to implement string-driven creation of instance objects
As the complexity of the software increases, the flexibility of the server system and the configuration flexibility of the business process will be greatly reduced

Embodiment Construction

[0016] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.

[0017] see figure 1 , is a schematic diagram of the steps of the method for dynamically instantiating C / C++ classes in the present invention. The present invention comprises the following steps:

[0018] Step 1. Define the structure of the information required for dynamic instantiation;

[0019] In the step 1, the structure of the information required for dynamic instantiation is defined: it includes information such as class name, pointer to the dynamic creation function, occupied memory size, etc., and a hash table for storing the information structure.

[0020] Step 2, define the first and second macro definitions;

[0021] In said step 2, define the first and the second macro definition: the first macro definition is a dynamic statement...

Abstract

The invention provides a method for instantiating C / C++ dynamically, which includes: the first step of defining a structure of information required by dynamic instantiation; the second step of defining a first macro definition and a second macro definition; the step 3 of defining an instantiation function; and the fourth step of calling the instantiation function and completing instantiation of a target by an input class name to be instantiated. The C / C++ class is instantiated dynamically by configuring data, and service processing can be realized by creating C / C++ targets according the instantiated class names in the configured data, and accordingly configurability of backstage services is realized, and system flexibility of servers and configuration flexibility of service procedures are greatly improved.

Description

technical field [0001] The invention relates to a method for dynamically instantiating C / C++, in particular to a method for dynamically instantiating C / C++ classes through configuration data. Background technique [0002] With the development of science and technology, C / C++ language has the characteristics of high efficiency and strong portability, and is widely used in software and system software development. But with the increasing complexity of software systems, the flexibility of server architecture is also increasing. In order to achieve the configurability of background services, it is necessary to instantiate C / C++ through configuration data, and instantiate through the C / C++ class name string read from the configuration. The C / C++ language itself does not have this feature, so it is impossible to create instance objects driven by strings. As the complexity of the software increases, the flexibility of the server system and the configuration flexibility of the bus...
