Wrapper around a member function pointer. The class instance whose member function to call is passed as a pointer to the operator().

  1. Wraps a non-const member function with no parameters.

  2. Wraps a const member function with no parameters.

  3. Wraps a non-const member function with a single parameter.

  4. Wraps a const member function with a single parameter.
