Detailed Description

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

Extends reflex::AbstractLexer<M>::Matcher for Flex-compatibility.

Constructor & Destructor Documentation

template<typename M >

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

inline

Construct a FlexLexer 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::FlexLexer< M >::Matcher::Matcher ( const char *  pattern, const Input &  input, FlexLexer *  lexer, const char *  opt = NULL  )

inline

Construct a FlexLexer 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 size_t reflex::FlexLexer< M >::Matcher::get ( char *  s, size_t  n  )

inlinevirtual

Read character sequences via a Flex-compatible virtual FlexLexer::LexerInput method.

template<typename M >

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

inlineprotectedvirtual

Check the Flex-compatible FlexLexer::yywrap method to determine if matcher should wrap input after EOF (lexer yywrap() should return 0 to wrap input after EOF).

Returns

true if FlexLexer::yywrap() == 0 indicating that input is wrapped after EOF

Reimplemented from reflex::AbstractLexer< M >::Matcher.
