Detailed Description

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

Unary function object for member functions without arguments.

Creates a function object from a member function without arguments (note, the single argument to this unary function object is the class instance itself).

Usage:

class A {
public:
    void f() { //...
    }
};
 
int main() {
    A a;
    NullaryMemberFunction<A,void> function_object(&A::f);
    function_object(a);
}

Template Parameters

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

NullaryMemberFunction()

template<typename C , typename R = void>

ecl::NullaryMemberFunction< C, R >::NullaryMemberFunction ( R(C::*)()  function )

inline

Unary function object constructor for member functions without arguments.

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

Parameters

function

: a void member function.

This ensures any children objects are deleted correctly.

A unary function object call.

Uses the specified class instance to redirect the function call to the void member function.

Parameters

class_object

: the member function's class instance.

Returns

R : the function's return value.

Implements ecl::UnaryFunction< C &, void >.
