This library is a further development of the Don Clugston’s project “Member Function Pointers and the Fastest Possible C++ Delegates” (http://www.codeproject.com/KB/cpp/FastDelegate.aspx).
Modification are mainly aimed to make this library useful for implementing the reflection library and data marshalling systems of SekaiFramework (http://github.com/mikhtonyuk/SekaiFramework).
Main feature of dynamic delegate library is a possibility to invoke a delegate using an array of arguments. For example:
void F1(int i) { ... }
auto deleg = make_delegate_dynamic(&F1);
int arg = 10;
void* args[] = { &arg };
// Calls F1
deleg.invoke(args, 0 /* no return value */ );
Dynamic invocation extension is separated from original zero-overhead delegates, so that they can be used in places where dynamic invocation is not required.
Performance of ordinary delegates left unchanged, only slightly reduced compile time thanks to code refactoring.
Dynamic delegates add a virtual table pointer size overhead, plus a virtual call overhead for eack invoke call.
