Last century six the seventies, along with the appearance of Object-Oriented Programming Language, the various software development methodologies of Object-oriented Programming Design and framework also arise at the historic moment and are developed rapidly.
The core part of Object-oriented Programming Design has been to propose the notion of " object ", by objective entity being abstracted into " object " with certain attribute and function, and by " object " encapsulated, the parameter interface of its attribute and the function of only opening to the outside world, make the programmer in the process of coding, do not need to know the method for object itself be attribute that how to realize and concrete how, and only need the parameter interface of allocating object, just can call object and finish specific function.
MFC (Microsoft Foundation Classes) commonly used at present is exactly a class libraries that comprises more than 100 class, and wherein, these classes are exactly the most frequently used object that arrives in the software development process.In programming process, except calling the parameter interface of these existing objects, to realize needed function, can also utilize the existing object of method from the MFC class libraries of " succession " to derive various self-defined objects, these self-defined objects are except attribute and function with existing object, can also have various self-defining attributes and function as required, thereby realize the expansion of object.
Yet, flourish along with software industry, software systems become and become increasingly complex.Software systems generally include a more than project that comprises a plurality of application examples, and therefore on stream, same class may need to be multiplexed in one or more application examples in the identical or different project.Because the difference of each applied environment, in general, the multiplexing of class can not only be realized by the code of duplicating, pasting class simply, also need manually adjust the interface parameters of class and the relevant parameter in the application example at different application examples, and the exploitation of software systems is finished by several slip-stick artists even a plurality of team collaboration usually, that is to say that a certain section code of being finished may be repeatedly multiplexing by different people.Because the disunity of class interface and program thread and applied environment there are differences, in the process of code reuse, the code of class often appears for example not duplicating fully easily, the perhaps interface parameters of unmodified class has perhaps only been revised the interface parameters of class and problems such as relevant parameter in the unmodified application example.This not only causes the error rate of program to increase greatly, returns follow-up maintenance and inspection work brings very big difficulty, has both delayed the construction cycle, has also increased cost of development.
