Friends And Related Function Documentation

friend class TAO_AMH_Response_Handler [friend]
 

Declare TAO_AMH_Response_Handler a friend.

The TAO_AMH_Response_Handler class needs to copy part of the state in a TAO_ServerRequest, however, we do not want to expose that state as public members of this class, neither do we want to add modifiers to the TAO_AMH_Response_Handler class that would allow us (the TAO_ServerRequest class) to set the state.

Lucky for us, C++ is a language for adult developers, and allow us to use the evil "friend" declaration.
