Detailed Description

template<typename ExprT>
struct cttl_impl::xtl_entity< ExprT >

Implements behavior of entity expression adaptor, which enforces non-empty match of the encapsulated sub-expression.

ExprT

Template parameter specifying type of grammar sub-expression object, determined by the C++ compiler at compile time.

Member Function Documentation

size_t bang_find (  UniverseT &  edge_  )  [inline]

Implements grammar evaluation method for 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 entity. Returns: evaluation result: if method succeeds, it returns absolute offset corresponding to the upper boundary of the matched entity. Otherwise, it returns UniverseT::string_T::npos, indicating that the evaluation method has failed. Definition at line 1131 of file xtl_op_impl.h.

size_t find (  UniverseT &  edge_  )  [inline]

Implements grammar evaluation method for symbol 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 entity. Returns: evaluation result: if method succeeds, it returns absolute offset corresponding to the upper boundary of the matched entity. Otherwise, it returns UniverseT::string_T::npos, indicating that the evaluation method has failed. Definition at line 1095 of file xtl_op_impl.h.

size_t match (  UniverseT &  edge_  )  [inline]

Implements grammar evaluation method for entity 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 entity. Returns: evaluation result: if method succeeds, it returns absolute offset corresponding to the upper boundary of the matched entity. Otherwise, it returns UniverseT::string_T::npos, indicating that the evaluation method has failed. Definition at line 1059 of file xtl_op_impl.h.
