Detailed Description

template<typename Left_exprT, typename Right_exprT>
struct cttl_impl::xtl_opbinminus< Left_exprT, Right_exprT >

Implements behavior of binary set complement operator.

Left_exprT

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

Right_exprT

Template parameter specifying type of right-hand-side grammar 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 fragment. Returns: evaluation result: if method succeeds, it returns absolute offset corresponding to the upper boundary of the matched fragment. Otherwise, it returns UniverseT::string_T::npos, indicating that the evaluation method has failed. Definition at line 2191 of file xtl_op_impl.h. References xtl_edge_offset_manager::first, xtl_edge_offset_manager::restore(), xtl_edge_offset_manager::save(), and xtl_edge_offset_manager::second.
