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
