Class factory registration method and device and electronic device

Abstract

The embodiment of the invention discloses a class factory registration method and device and an electronic device. The class factory registration method includes: creating a custom program segment ina source code, and creating a first program area, a second program area, and a third program area in the custom program segment, wherein an address of global data created in the first program area isin front that of the second program area, and the address of the global data created in the second program area is in front of that of the third program area; creating a list header pointer in the first program area, and creating a list tail pointer in the third program area; and registering a preset class factory in the second program area. The inflexibility that in the conventional class factorymode, when a global variable is used to perform class factory registration, all the class registration codes can be written in only one code file is improved, the characteristics of the program segment and the program area are used to achieve automatic registration of the class factory, the class factory can be registered in any source file of a project, and the flexibility of the class factory mode is greatly improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a factory registration method, device and electronic equipment. Background technique [0002] In large-scale software projects, various design patterns are often used to ensure the stability of the entire project system, the readability of source code, and the ease of maintenance in the later stage. Among them, the class factory pattern is a point commonly used in these design patterns. The advantage of the class factory pattern is that it can create class objects more conveniently and flexibly. [0003] The core of the implementation of the class factory pattern is to register all classes in a global address, through which all classes to be created can be enumerated. In the implementation of the traditional solution, it is mainly to add classes one by one to a global variable, and then find the class to be created by traversing all the items in the global variable.
