BloombergLP::bdlf::MemFnInstance

This class encapsulates a member function pointer having the parameterized PROTOTYPE and a value of the parameterized INSTANCE type, which can be either be the type of object referred to by the PROTOTYPE, or a pointer to one, such that the member function pointer can be invoked on the wrapped instance in syntactically the same manner as a free function pointer. Zero to fourteen additional arguments may be specified depending on the PROTOTYPE. Note that whether INSTANCE is a pointer or an object is determined by whether it has pointer semantics or not (as determined by the bslmf::HasPointerSemantics type trait). Also note that if INSTANCE is an object that does not have pointer semantics, PROTOTYPE must be const-qualified.
