//						FastDelegate.h 
//	Efficient delegates in C++ that generate only two lines of asm code!
//  Documentation is found at http://www.codeproject.com/cpp/FastDelegate.asp
//
//						- Don Clugston, Mar 2004.
//		Major contributions were made by Jody Hagins.
// History:
// 24-Apr-04 1.0  * Submitted to CodeProject. 
// 28-Apr-04 1.1  * Prevent most unsafe uses of evil static function hack.
//				  * Improved syntax for horrible_cast (thanks Paul Bludov).
//				  * Tested on Metrowerks MWCC and Intel ICL (IA32)
//				  * Compiled, but not run, on Comeau C++ and Intel Itanium ICL.
//	27-Jun-04 1.2 * Now works on Borland C++ Builder 5.5
//				  * Now works on /clr "managed C++" code on VC7, VC7.1
//				  * Comeau C++ now compiles without warnings.
//				  * Prevent the virtual inheritance case from being used on 
//					  VC6 and earlier, which generate incorrect code.
//				  * Improved warning and error messages. Non-standard hacks
//					 now have compile-time checks to make them safer.
//				  * implicit_cast used instead of static_cast in many cases.
//				  * If calling a const member function, a const class pointer can be used.
//				  * MakeDelegate() global helper function added to simplify pass-by-value.
//				  * Added fastdelegate.clear()
// 16-Jul-04 1.2.1* Workaround for gcc bug (const member function pointers in templates)
// 30-Oct-04 1.3  * Support for (non-void) return values.
//				  * No more workarounds in client code!
//					 MSVC and Intel now use a clever hack invented by John Dlugosz:
//				     - The FASTDELEGATEDECLARE workaround is no longer necessary.
//					 - No more warning messages for VC6
//				  * Less use of macros. Error messages should be more comprehensible.
//				  * Added include guards
//				  * Added FastDelegate::empty() to test if invocation is safe (Thanks Neville Franks).
//				  * Now tested on VS 2005 Express Beta, PGI C++
// 24-Dec-04 1.4  * Added DelegateMemento, to allow collections of disparate delegates.
//                * <,>,<=,>= comparison operators to allow storage in ordered containers.
//				  * Substantial reduction of code size, especially the 'Closure' class.
//				  * Standardised all the compiler-specific workarounds.
//                * MFP conversion now works for CodePlay (but not yet supported in the full code).
//                * Now compiles without warnings on _any_ supported compiler, including BCC 5.5.1
//				  * New syntax: FastDelegate< int (char *, double) >. 
// 14-Feb-05 1.4.1* Now treats =0 as equivalent to .clear(), ==0 as equivalent to .empty(). (Thanks elfric).
//				  * Now tested on Intel ICL for AMD64, VS2005 Beta for AMD64 and Itanium.
// 30-Mar-05 1.5  * Safebool idiom: "if (dg)" is now equivalent to "if (!dg.empty())"
//				  * Fully supported by CodePlay VectorC
//                * Bugfix for Metrowerks: empty() was buggy because a valid MFP can be 0 on MWCC!
//                * More optimal assignment,== and != operators for static function pointers.

// (a) Error messages are generated by typdefing an array of negative size to

// (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

//
// Workaround for (1): Declare a dummy type 'DefaultVoid' which we use
//   when we'd like to use 'void'. We convert it into 'void' and back
//   using the templates DefaultVoidToVoid<> and VoidToDefaultVoid<>.
// Workaround for (2): On VC6, the code for calling a void function is
//   identical to the code for calling a non-void function in which the
//   return value is never used, provided the return value is returned
//   in the EAX register, rather than on the stack. 
//   This is true for most fundamental types such as int, enum, void *.
//   Const void * is the safest option since it doesn't participate

//						Fast Delegates, part 2:
//
//	Define the delegate storage, and cope with static functions
//
////////////////////////////////////////////////////////////////////////////////

// DelegateMemento -- an opaque structure which can hold an arbitary delegate.
// It knows nothing about the calling convention or number of arguments used by
// the function pointed to.
// It supplies comparison operators so that it can be stored in STL collections.
// It cannot be set to anything other than null, nor invoked directly: 
//   it must be converted to a specific delegate.

// Implementation:
// There are two possible implementations: the Safe method and the Evil method.
//				DelegateMemento - Safe version
//
// This implementation is standard-compliant, but a bit tricky.
// A static function pointer is stored inside the class. 
// Here are the valid values:
// +-- Static pointer --+--pThis --+-- pMemFunc-+-- Meaning------+
// |   0				|  0       |   0        | Empty          |
// |   !=0              |(dontcare)|  Invoker   | Static function|
// |   0                |  !=0     |  !=0*      | Method call    |
// +--------------------+----------+------------+----------------+
//  * For Metrowerks, this can be 0. (first virtual function in a 
//       single_inheritance class).
// When stored stored inside a specific delegate, the 'dontcare' entries are replaced
// with a reference to the delegate itself. This complicates the = and == operators
// for the delegate class.

//				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.

//						Fast Delegates, part 3:
//
//				Wrapper classes to ensure type safety
//
////////////////////////////////////////////////////////////////////////////////


// Once we have the member function conversion templates, it's easy to make the
// wrapper classes. So that they will work with as many compilers as possible, 
// the classes are of the form
//   FastDelegate3<int, char *, double>
// They can cope with any combination of parameters. The max number of parameters
// allowed is 8, but it is trivial to increase this limit.
// Note that we need to treat const member functions seperately.
// All this class does is to enforce type safety, and invoke the delegate with
// the correct list of parameters.

// Because of the weird rule about the class of derived member function pointers,
// you sometimes need to apply a downcast to the 'this' pointer.
// This is the reason for the use of "implicit_cast<X*>(pthis)" in the code below. 
// If CDerivedClass is derived from CBaseClass, but doesn't override SimpleVirtualFunction,
// without this trick you'd need to write:
//		MyDelegate(static_cast<CBaseClass *>(&d), &CDerivedClass::SimpleVirtualFunction);
// but with the trick you can write
//		MyDelegate(&d, &CDerivedClass::SimpleVirtualFunction);

// RetType is the type the compiler uses in compiling the template. For VC6,
// it cannot be void. DesiredRetType is the real type which is returned from
// all of the functions. It can be void.

// Implicit conversion to "bool" is achieved using the safe_bool idiom,
// using member data pointers (MDP). This allows "if (dg)..." syntax
// Because some compilers (eg codeplay) don't have a unique value for a zero
// MDP, an extra padding member is added to the SafeBool struct.
// Some compilers (eg VC6) won't implicitly convert from 0 to an MDP, so
// in that case the static function constructor is not made explicit; this
// allows "if (dg==0) ..." to compile.
