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

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))
