Detailed Description

template<typename C, typename A, typename R = void>
class ecl::UnaryMemberFunction< C, A, R >

Binary function object for unary member functions.

Creates a function object from a unary member function.

Usage:

class A {
public:
    void f(int i) { //...
    }
};

int main() {
    A a;
    UnaryMemberFunction<A,int,void> function_object(&A::f);
    function_object(a,1);
}

Template Parameters

C	: the member function's class type.
A	: the member function's argument type.
R	: the return type.

template<typename C, typename A, typename R = void>

ecl::UnaryMemberFunction< C, A, R >::UnaryMemberFunction ( R(C::*)(A)  function )

inline

Binary function object constructor for unary member functions.

Accepts a unary member function, and builds the function object around it.

Parameters

function

: a unary member function.

R ecl::UnaryMemberFunction< C, A, R >::operator() ( C &  class_object, A  a  )

inlinevirtual

This ensures any children objects are deleted correctly.

A binary function object call.

Uses the specified class instance and argument to redirect the function call to the unary member function.

Parameters

class_object	: the member function's class instance.
a	: the member function's argument value.

Returns

R : the function's return value.

Implements ecl::BinaryFunction< C &, A, R >.
