fcppt::parse::repetition< Parser > Class Template Reference

Detailed Description

template<typename Parser>
class fcppt::parse::repetition< Parser >

Tries a parser repeatedly, producing a vector of results.

Let p be a parser and rep = repetition{p}. Initially, the result r is the empty vector. A single parsing step consists of the following actions: First, the current position pos is saved. Then, the skipper is run. After that, the parser p is tried. If it succeeds with result s, then s is added to r. These steps continue as long as p does not return an error. Once this happens, if the returned error is fatal, then rep also returns a fatal error. Otherwise, rep backtracks to pos and returns r.
