The binary operator .* binds its second operand, which shall be of the type of "pointer to member of T" (where T is a completely-defined class type) to its first operand, which shall be of class T or of a class of which T is an unambiguous and accessible base class. The result i...
The binary operator –>* combines its first operand, which must be a pointer to an object of class type, with its second operand, which must be a pointer-to-member type.In an expression containing the .* operator, the first operand must be of the class type of, and be accessible to,...

Pointers to functionsA pointer to function can be initialized with an address of a non-member function or a static member function. Because of the function-to-pointer implicit conversion, the address-of operator is optional: void f(int); void (*p1)(int) = &f; void (*p2)(int) = f;...

You can change the value and behaviour of these pointers on runtime. That means, you can point it to other member function or member variable. To have pointer to data member and member functions you need to make them public. ← Prev ...
It defines its member function operator() as returning (* pfunc)(Left, right).RemarksA binary function pointer is a function object and may be passed to any C++ Standard Library algorithm that is expecting a binary function as a parameter, but it is not adaptable. To use it with an ...
pointer/reference to an object along with a pointer to a member function, and operator() calls the member function on the stored object. Alternatively, check out boost::function available at http://www.boost.org/. If you're using Borland and don't care about writing ANSI compatible code,...
Member constants value [static] true if T is a member function pointer type, false otherwise (public static member constant) Member functions operator bool converts the object to bool, returns value (public member function) operator() (C++14) returns value (public member function) Mem...
Operator -> for shared pointer Hi I have a member variable T* m_ptr into templated class. This is in line with shared pointer implementation. My query is operator overloaded function as below: T* operator->() { return m_ptr; } Why this pointer directly call method ? Should it not be...
