On this basis, it expounds realization of each function entity in detail. Finally, it gives a brief analysis of virtual call center's advantage and shortage, and discusses its applied foreground.

We call this interface virtual because there is no "real" service provider for it.
我们将调用此虚拟接口，因为没有为它提供真正的服务提供程序。
Research has shown that most virtual invocations have only a single target for all receiver objects, and JIT compilers can generate more-efficient code for a direct call than for a virtual invocation.
研究表明：大多数虚调用只有一个目标对应于所有的接收方对象，而JIT编译器可以为直接调用生成比虚调用更有效率的代码。
A virtual method invocation, for example, involves looking at the class of the receiver object for the call to discover which actual target implements the virtual method for the receiver object.
例如，一个虚方法调用需要查看接收方对象的类调用，以便找出哪个实际目标实现了接收方对象的虚方法。
