[pure virtual]

Invokes the method encapsulated by the command, passing along the passed argument (if any). Users of classes derived from this class must ensure that the resulting invocation can tolerate a null void pointer being passed, or otherwise ensure that this will never occur.

Implemented in ACE_Member_Function_Command< RECEIVER >, ACE_Noop_Command, and ACE_Command_Callback< RECEIVER, ACTION >.
