Function repeat

boost::xpressive::repeat — Repeat a sub-expression multiple times.

Synopsis

template<unsigned int Min, unsigned int Max, typename Xpr> 
  unspecified repeat(Xpr const & xpr);
template<unsigned int Count, typename Xpr2> 
  unspecified repeat(Xpr2 const & xpr);

Description

There are two forms of the repeat<>() function template. To match a sub-expression N times, use repeat<N>(xpr). To match a sub-expression from M to N times, use repeat<M,N>(xpr).

The repeat<>() function creates a greedy quantifier. To make the quantifier non-greedy, apply the unary minus operator, as in -repeat<M,N>(xpr).

Parameters:

xpr

The sub-expression to repeat.
