    • An aspect oriented system for implementing the Design by Contract software development methodology is provided in which preconditions and postconditions defining the contract need not be coded into the program modules being developed. Rather, an aspect is provided which encapsulates these preconditions and postconditions. This behavior may easily and transparently be forced onto the resource by compiling the object class for the program module along with the contract aspect. When the software program in which the program modules is used is no longer needed, the preconditions and postconditions are removed simply by recompiling the resource object classes without the aspect.
    • 提供了一种实现“按合同设计”软件开发方法的面向方面的系统,其中定义合同的先决条件和后置条件不需要被编码到正在开发的程序模块中。 相反,提供封装这些前提条件和后置条件的方面。 通过编译程序模块的对象类以及合同方面,可以轻松,透明地将此行为强制转换到资源上。 当不再需要使用程序模块的软件程序时,通过重新编译没有方面的资源对象类,将删除前提条件和后置条件。
