Function trim_right_copy

Function trim_right_copy_if

boost::algorithm::trim_right_copy_if — Right trim - parametric.

Synopsis

// In header: <boost/algorithm/string/trim.hpp>


template<typename OutputIteratorT, typename RangeT, typename PredicateT> 
  OutputIteratorT 
  trim_right_copy_if(OutputIteratorT Output, const RangeT & Input, 
                     PredicateT IsSpace);
template<typename SequenceT, typename PredicateT> 
  SequenceT trim_right_copy_if(const SequenceT & Input, PredicateT IsSpace);

Description

Remove all trailing spaces from the input. The supplied predicate is used to determine which characters are considered spaces. The result is a trimmed copy of the input. It is returned as a sequence or copied to the output iterator

	Note
	The second variant of this function provides the strong exception-safety guarantee

Parameters:

`Input`	An input range
`IsSpace`	A unary predicate identifying spaces
`Output`	An output iterator to which the result will be copied

Returns:

An output iterator pointing just after the last inserted character or a copy of the input
