fastdelegate Namespace

General tricks used in this code

(a) Error messages are generated by typdefing an array of negative size to generate compile-time errors. (b) Warning messages on MSVC are generated by declaring unused variables, and enabling the "variable XXX is never used" warning. (c) Unions are used in a few compiler-specific cases to perform illegal casts. (d) For Microsoft and Intel, when adjusting the 'this' pointer, it's cast to (char *) first to ensure that the correct number of *bytes* are added.

Classes

	Name	Description
	DelegateMemento	DelegateMemento - Evil version For compilers where data pointers are at least as big as code pointers, it is possible to store the function pointer in the this pointer, using another horrible_cast. In this case the DelegateMemento implementation is simple: +--pThis --+-- pMemFunc-+-- Meaning---------------------+ \| 0 \| 0 \| Empty \| \| !=0 \| !=0* \| Static function or method call\| +----------+------------+-------------------------------+ For Metrowerks, this can be 0. (first virtual function in a single_inheritance class). Note that the Sun C++ and MSVC documentation explicitly state that they support static_cast between void * and function pointers.

Macros

Name	Description
FASTDLGT_RETTYPE	Workaround for VC6. VC6 needs void return types converted into DefaultVoid. GCC 3.2 and later won't compile this unless it's preceded by 'typename', but VC6 doesn't allow 'typename' in this context. So, I have to use a macro.
