size_t match (  UniverseT const &  edge_  )  const [inline]

Implements grammar evaluation method for symbol match algorithm, starting at the upper boundary of the parseable universe. UniverseT Template parameter specifying type of the parseable universe. Can be either cttl::const_edge or cttl::edge. Parameters: edge_  reference to the parseable universe. Returns: evaluation result: if method succeeds, it returns absolute offset corresponding to the upper boundary of the matched symbol. Otherwise, it returns UniverseT::string_T::npos, indicating that the evaluation method has failed. Definition at line 557 of file xtl_primary.h.
