Detailed Description

template<class BinaryFun, class UnaryFun1, class UnaryFun2>
struct utilmm::binary_compose_2< BinaryFun, UnaryFun1, UnaryFun2 >

Binary functor composition with two unary functors.

This class helps programmers to compose one std::binary_function with two std::unary_function

Parameters:

	BinaryFun	The binary functor
	UnaryFun1	The first unary function
	UnaryFun2	The second unary function

The resulting class is a functor corresponding to BinaryFun(UnaryFun1(x), UnaryFun2(y))

Precondition:

The result_type of UnaryFun1 must be default convertible to the first_argument_type of BinaryFun

The result_type of UnaryFun2 must be default convertible to the second_argument_type of BinaryFun

		UnaryFun2 const &	two
	)			[inline]

Constructor.

Create a new instance having the three functors instances to compose.

Parameters:

	bin	The binary functor
	one	The first unary functor
	two	The second unary functor

Postcondition:

newly created instance will have exactly the same behavior as bin(one(x), two(y)).

Composition function.

This function create a new binary_compose_2 based on one binary_function and two unary functions. It only ease the declaration of binary_compose_2 instances.

Parameters:

	f	The binary function
	a	The first unary function
	b	The second unary function

Returns:

a functor corresponding to f(a(x), b(y))
