// 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.

Implementations of Member Function Pointers
So, how do compilers typically implement member function pointers?
Here are some results obtained by applying the sizeof operator to
various structures (an int, a void * data pointer,
a code pointer (i.e., a pointer to a static function),
and a member function pointer to a class
with single-, multiple-, virtual- inheritance,
or unknown (i.e., forward declared)) for
a variety of 32, 64 and 16-bit compilers.

// Dlugosz's trick is to make the codeptr point to a probe function which
// returns the 'this' pointer that was used.
// Define a generic class that uses virtual inheritance.
// It has a trival member function that returns the value of the 'this' pointer.
// Microsoft/Intel MFPs上一个非常重要的特点是：我们发现-不管其他成员的值是多少，
//‘m_codeptr’成员“总是”被调用（这对于其他编译器则不是这样，
// 例如gcc，如果一个虚函数被调用，它从vtable中获取函数地址）
// Dlugosz的技巧是使codeptr指针指向一个探针（probe）函数，该函数返回值是使用的‘this’指针。

// 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.
// DelegateMemento（代理备忘录）--一个保存任意delegate的不透明的结构。
// 它对函数指向的调用转换或者参数的数目一无所知。
// 它提供比较操作符，因此可以存放在stl中。
// 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. - 这个实现是标准兼容的,但有点棘手
// 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

// 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

// 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.
// 一旦我们有了 成员函数转换模板，生成封装类则是非常容易。
// 因此他们将适用于尽可能多的编译器。
// 类将是这样的形式：
// FastDelegate3<int, char *, double>
// 他们处理不同组合的参数，最大参数个数是8，但是允许增加参数个数限制。
// 注意我们需要单独处理const 成员函数。
// 类做的所有工作都是强化类型安全，及以正确的参数列表来调用委托
// 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);
// 对于那些有派生成员函数指针的类来说，你有时需要对‘this’指针进行 downcast
// 这就是下面的代码会用到implicit_cast<X*>(pthis)的原因
// 如果CDerivedClass派生于CBaseClass，但是并没有重载SimpleVirtualFunction，
// 若没有这个技巧，你需要这样写：
// MyDelegate(static_cast<CBaseClass *>(&d), &CDerivedClass::SimpleVirtualFunction);
// 但是用的话，你就可以这样：
// 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.
// RetType类型是编译器在编译模板所需。对于vc，他不能是void。
// DesiredRetType是从所有函数返回的真正的类型。它可以是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.
// 隐式转换为“bool”由safe_bool来完成,使用成员函数指针（MDP）
// 这允许“if(dg)”语法，因为一些编译器（如 codeplay）对0没有唯一值

2.FastDelegateBind.h
// FastDelegateBind.h
// Helper file for FastDelegates. Provides bind() function, enabling
// FastDelegates to be rapidly compared to programs using boost::function and boost::bind.
//
// Documentation is found at http://www.codeproject.com/cpp/FastDelegate.asp
//
// Original author: Jody Hagins.
// Minor changes by Don Clugston.
//
// Warning: The arguments to 'bind' are ignored! No actual binding is performed.
// The behaviour is equivalent to boost::bind only when the basic placeholder
// arguments _1, _2, _3, etc are used in order.
//
// HISTORY:
// 1.4 Dec 2004. Initial release as part of FastDelegate 1.4.

// FastDelegate bind()
//
// bind() helper function for boost compatibility.
// (Original author: Jody Hagins).
// bind()帮助类，以与boost相兼容（原始作者：Jody Hagins）
//
// Add another helper, so FastDelegate can be a dropin replacement
// for boost::bind (in a fair number of cases).
// Note the elipses, because boost::bind() takes place holders
// but FastDelegate does not care about them. Getting the place holder
// mechanism to work, and play well with boost is a bit tricky, so
// we do the "easy" thing...
// Assume we have the following code...
// using boost::bind;
// bind(&Foo:func, &foo, _1, _2);
// we should be able to replace the "using" with...
// using fastdelegate::bind;
// and everything should work fine...
