Member Function Documentation

size_t internal_find (  UniverseT &  edge_  )  [inline]

Implements search grammar evaluation method. 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. Postcondition: If method succeeds, the universe, specified by the edge_ parameter, is consumed accordingly to the size of the matched symbol: // 1. The ending position of the matched symbol is set: edge_.first.offset( end_offset ); // 2. Starting position of the matched symbol is returned: return begin_offset; 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 1726 of file xtl_primary.h.
