Detailed Description

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

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

Constructor & Destructor Documentation

template<typename M >

reflex::AbstractLexer< M >::Matcher::Matcher ( const typename M::Pattern &  pattern, const Input &  input, AbstractLexer *  lexer, const char *  opt = NULL  )

inline

Construct a lexer matcher from a matcher's pattern type.

Parameters

pattern	regex pattern to instantiate matcher class M(pattern, input)
input	the reflex::Input to instantiate matcher class M(pattern, input)
lexer	points to the instantiating lexer class
opt	option 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  )

inline

Construct a lexer matcher from a string pattern.

Parameters

pattern	regex pattern to instantiate matcher class M(pattern, input)
input	the reflex::Input to instantiate matcher class M(pattern, input)
lexer	points to the instantiating lexer class
opt	option string of the form (A|N|T(=[[:digit:]])?|;)*

Member Function Documentation

template<typename M >

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

inlineprotectedvirtual

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.
