Inheritance diagram for glift::Command:

List of all members.

Detailed Description

command.h - A simple "Command" object that allows for 'void name()' member callbacks.

Taken from pp. 239-241 of "Design Patterns: Elements of
Reusable Object-Oriented Software" by Gamma, Helm, Johnson, and Vlissides.
Copywrite 1995, Addison Wessley.
To make class that takes either a C-style function pointer or a
pointer-to-member (PTM), have it take a Command* and either instantiate a
"Command0" or a "MemberCommand0".
Instantiate 'MemberCommand0' with an instance of the class containing
the callback method and a pointer to the callback name.

Example:

        AClass a;
        MemberCommand0<AClass>* callback = new MemberCommand0(&a, &AClass::daCallBack);
        callback->execute();    //Calls a.daCallBack()
