Detailed Description

template<typename M>
class reflex::AbstractLexer< M >::Matcher

Extend matcher class M with a member pointing to the instantiating lexer class.

optoption string of the form (A|N|T(=[[:digit:]])?|;)*
template<typename M >
reflex::AbstractLexer< M >::Matcher::Matcher ( const char *  pattern,
const Input input,
AbstractLexer lexer,
const char *  opt = NULL

Member Function Documentation

template<typename M >
virtual bool reflex::AbstractLexer< M >::Matcher::wrap ( )

Returns true if matcher should wrap input after EOF (lexer wrap() should return 0 to wrap input after EOF).

Returns
true if reflex::AbstractLexer::wrap() == 0 indicating that input is wrapped after EOF

Reimplemented in reflex::FlexLexer< M >::Matcher.
