Constructor & Destructor Documentation

xtl_opunarstar (  ExprT const &  expr_, size_t  upper_limit_ = 0 )  [inline]

Constructs and initializes the object. Parameters: expr_  immutable reference to CTTL grammar expression of the operand. upper_limit_  If not zero, suggests the upper limit for a number of matches. Definition at line 359 of file xtl_op_impl.h.

Member Function Documentation

size_t bang_find (  UniverseT &  edge_  )  [inline]

Implements grammar evaluation method for Kleene star repeatable search 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. Postcondition: If method succeeds, the universe, specified by the edge_ parameter, gets consumed accordingly to the size of the matched symbols. Returns: evaluation result: if method succeeds, it returns absolute offset corresponding to the upper boundary of the matched symbols. Otherwise, it returns UniverseT::string_T::npos, indicating that the evaluation method has failed. Definition at line 548 of file xtl_op_impl.h.

size_t find (  UniverseT &  edge_  )  [inline]

Implements grammar evaluation method for Kleene star search 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. Postcondition: If method succeeds, the universe, specified by the edge_ parameter, gets consumed accordingly to the size of the matched symbols. Returns: evaluation result: if method succeeds, it returns absolute offset corresponding to the upper boundary of the matched symbols. Otherwise, it returns UniverseT::string_T::npos, indicating that the evaluation method has failed. Definition at line 469 of file xtl_op_impl.h.

size_t match (  UniverseT &  edge_  )  [inline]

Implements grammar evaluation method for Kleene star 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. Postcondition: If method succeeds, the universe, specified by the edge_ parameter, gets consumed accordingly to the size of the matched symbols. Returns: evaluation result: if method succeeds, it returns absolute offset corresponding to the upper boundary of the matched symbols. Otherwise, it returns UniverseT::string_T::npos, indicating that the evaluation method has failed. Definition at line 391 of file xtl_op_impl.h.
