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

//\r
//      Define the delegate storage, and cope with static functions\r
//\r
////////////////////////////////////////////////////////////////////////////////\r
\r
// DelegateMemento -- an opaque structure which can hold an arbitary delegate.\r
// It knows nothing about the calling convention or number of arguments used by\r
// the function pointed to.\r
// It supplies comparison operators so that it can be stored in STL collections.\r
// It cannot be set to anything other than null, nor invoked directly: \r
//   it must be converted to a specific delegate.\r
\r
// Implementation:\r
// There are two possible implementations: the Safe method and the Evil method.\r
//                              DelegateMemento - Safe version\r
//\r
// This implementation is standard-compliant, but a bit tricky.\r
// A static function pointer is stored inside the class. \r
// Here are the valid values:\r
// +-- Static pointer --+--pThis --+-- pMemFunc-+-- Meaning------+\r
// |   0                                |  0       |   0        | Empty          |\r
// |   !=0              |(dontcare)|  Invoker   | Static function|\r
// |   0                |  !=0     |  !=0*      | Method call    |\r
// +--------------------+----------+------------+----------------+\r
//  * For Metrowerks, this can be 0. (first virtual function in a \r
//       single_inheritance class).\r
// When stored stored inside a specific delegate, the 'dontcare' entries are replaced\r
// with a reference to the delegate itself. This complicates the = and == operators\r
// for the delegate class.\r
\r
//                              DelegateMemento - Evil version\r
//\r
// For compilers where data pointers are at least as big as code pointers, it is \r
// possible to store the function pointer in the this pointer, using another \r
// horrible_cast. In this case the DelegateMemento implementation is simple:\r
// +--pThis --+-- pMemFunc-+-- Meaning---------------------+\r
// |    0     |  0         | Empty                         |\r
// |  !=0     |  !=0*      | Static function or method call|\r
// +----------+------------+-------------------------------+\r
//  * For Metrowerks, this can be 0. (first virtual function in a \r
//       single_inheritance class).\r
// Note that the Sun C++ and MSVC documentation explicitly state that they \r
// support static_cast between void * and function pointers.\r

//\r
//                              Wrapper classes to ensure type safety\r
//\r
////////////////////////////////////////////////////////////////////////////////\r
\r
\r
// Once we have the member function conversion templates, it's easy to make the\r
// wrapper classes. So that they will work with as many compilers as possible, \r
// the classes are of the form\r
//   FastDelegate3<int, char *, double>\r
// They can cope with any combination of parameters. The max number of parameters\r
// allowed is 8, but it is trivial to increase this limit.\r
// Note that we need to treat const member functions seperately.\r
// All this class does is to enforce type safety, and invoke the delegate with\r
// the correct list of parameters.\r
\r
// Because of the weird rule about the class of derived member function pointers,\r
// you sometimes need to apply a downcast to the 'this' pointer.\r
// This is the reason for the use of "implicit_cast<X*>(pthis)" in the code below. \r
// If CDerivedClass is derived from CBaseClass, but doesn't override SimpleVirtualFunction,\r
// without this trick you'd need to write:\r
//              MyDelegate(static_cast<CBaseClass *>(&d), &CDerivedClass::SimpleVirtualFunction);\r
// but with the trick you can write\r
//              MyDelegate(&d, &CDerivedClass::SimpleVirtualFunction);\r
\r
// RetType is the type the compiler uses in compiling the template. For VC6,\r
// it cannot be void. DesiredRetType is the real type which is returned from\r
// all of the functions. It can be void.\r
\r
// Implicit conversion to "bool" is achieved using the safe_bool idiom,\r
// using member data pointers (MDP). This allows "if (dg)..." syntax\r
// Because some compilers (eg codeplay) don't have a unique value for a zero\r
// MDP, an extra padding member is added to the SafeBool struct.\r
// Some compilers (eg VC6) won't implicitly convert from 0 to an MDP, so\r
// in that case the static function constructor is not made explicit; this\r
// allows "if (dg==0) ..." to compile.\r
