Detailed Description

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

Nullary function object for bound unary global/static functions.

Binds the argument to a unary global/static function and uses this to construct a nullary function object.

Usage:

void f(int i) {}

int main() {
    BoundUnaryFreeFunction<int,void> function_object(f,1);
    function_object();
}

Note, often the use of generateFunctionObject is simpler.

Template Parameters

A	: the type of the argument to be bound.
R	: the return type.

Constructor & Destructor Documentation

template<typename A, typename R = void>

ecl::BoundUnaryFreeFunction< A, R >::BoundUnaryFreeFunction ( R(*)(A)  function, A  a  )

inline

Binds a unary function and creates a nullary function object.

Accepts both the function and a value for its single argument, binds them and creates a nullary function object.

Parameters

function	: the unary global/static function.
a	: the argument to bind.

R ecl::BoundUnaryFreeFunction< A, R >::operator() ( )

inlinevirtual

This ensures any children objects are deleted correctly.

A nullary function object call.

Redirects the function object call to the bound global/static function.

Returns

R : the function's return value.

Implements ecl::NullaryFunction< R >.
