## Detailed Description

### template<class RECEIVER, class ACTION>
class ACE_Command_Callback< RECEIVER, ACTION >

Defines a class template that allows us to invoke a GOF command style callback to an object without knowing anything about the object except its type.

This class declares an interface to execute operations, binding a RECEIVER object with an ACTION. The RECEIVER knows how to implement the operation. A class can invoke operations without knowing anything about it, or how it was implemented.
