Function template swap

boost::xpressive::swap — Swaps the contents of two basic_regex objects.

Synopsis

// In header: <boost/xpressive/basic_regex.hpp>


template<typename BidiIter> 
  void swap(basic_regex< BidiIter > & left, basic_regex< BidiIter > & right);

Description

	Note
	This is a shallow swap that does not do reference tracking. If you embed a `basic_regex` object by reference in another regular expression and then swap its contents with another `basic_regex` object, the change will not be visible to the enclosing regular expression. It is done this way to ensure that swap() cannot throw.

Parameters:

`left`	The first `basic_regex` object.
`right`	The second `basic_regex` object.

Throws:

Will not throw.
