Detailed Description

template<class Operation1, class Operation2>
class regina::stl::unary_compose< Operation1, Operation2 >

An adaptable unary function used to compose two unary functions.

This class is for use with the Standard Template Library.

The composition of functions func1 and func2 is the function comp for which comp(x) == func1(func2(x)).

Precondition:

Both template arguments are themselves adaptable unary functions.

Type Operation1::argument_type is the same as (or can be constructed from) type Operation2::result_type.

Python:

Not present.

Author:

This class was taken and modified from the Standard Template Library (http://www.stlport.org/).

template<class Operation1, class Operation2>

regina::stl::unary_compose< Operation1, Operation2 >::unary_compose	(	const Operation1 &	x,
		const Operation2 &	y
	)			[inline]

Creates a new composition function.

The new function comp will satisfy comp(arg) == x(y(arg)).

Parameters:

	x	the first function to use in the composition.
	y	the second function to use in the composition.
