/*! \file Defines generic split algorithms. Split algorithms can be used to divide a sequence into several part according to a given criteria. Result is given as a 'container of containers' where elements are copies or references to extracted parts. There are two algorithms provided. One iterates over matching substrings, the other one over the gaps between these matches. */ namespace boost { namespace algorithm { // iterate find ---------------------------------------------------// //!

In each iteration new match is found and added to the result. \param Result A 'container container' to contain the result of search.
