We have noted that the design of a large portion of the Standard C++ Library is in many ways not object-oriented. On the other hand, C++ excels as a language for manipulating objects. How do we integrate the Standard Library's non-object-oriented architecture with C++'s strengths as a language for manipulating objects?</P><P>The key is to use the right tool for each task. Object-oriented design methods and programming techniques are almost without peer as guideposts in the development of large, complex software. For the large majority of programming tasks, object-oriented techniques will remain the preferred approach. And products such as Rogue Wave's <I>Tools.h++ 7.0</I>, which encapsulates the Standard C++ Library with a familiar object-oriented interface, will provide you with the power of the Library and the advantages of object-orientation. </P><P>Use Standard C++ Library components directly when you need flexibility and/or highly efficient code. Use the more traditional approaches to object-oriented design, such as encapsulation and inheritance, when you need to model larger problem domains, and knit all the pieces into a full solution. When you need to devise an architecture for your application, <I>always</I> consider the use of encapsulation and inheritance to compartmentalize the problem. But if you discover that you need an efficient data structure or algorithm for a compact problem, such as data stream manipulation in drivers (the kind of problem that often resolves to a single class), look to the Standard C++ Library. The Standard C++ Library excels in the creation of reusable classes, where low-level constructs are needed, while traditional OOP techniques really shine when those classes are combined to solve a larger problem.</P><P>In the future, most libraries will use the Standard C++ Library as their foundation. By using the Standard C++ Library, either directly or through an encapsulation such as <I>Tools.h++ 7.0</I>, you help ensure interoperability. This is especially important in large projects that may rely on communication between several libraries. A good rule of thumb is to use the highest encapsulation level available to you, but make sure that the Standard C++ Library is available as the base for interlibrary communication and operation. </P><P>The C++ language supports a wide range of programming approaches because the problems we need to solve require that range. The language, and now the Standard C++ library that supports it, are designed to give you the power to approach each unique problem from the best possible angle. The Standard C++ Library, when combined with more traditional OOP techniques, puts a very flexible tool into the hands of anyone building a collection of C++ classes, whether those classes are intended to stand alone as a library or are tailored to a specific task.</P><HR><A HREF="wha_3608.htm"><IMG SRC="images/prev.gif"></A> <A HREF="booktoc1.htm"><IMG SRC="images/toc.gif"></A><A HREF="tindex1.htm"><IMG SRC="images/tindex.gif"></A><A HREF="rea_7538.htm"><IMG SRC="images/next.gif"></A><P>©Copyright 1996, Rogue Wave Software, Inc.</P></BODY></HTML>⌨️ 快捷键说明
