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
patternregex pattern to instantiate matcher class M(pattern, input)
inputthe reflex::Input to instantiate matcher class M(pattern, input)
lexerpoints to the instantiating lexer class
optoption 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
patternregex pattern to instantiate matcher class M(pattern, input)
inputthe reflex::Input to instantiate matcher class M(pattern, input)
lexerpoints to the instantiating lexer class
optoption 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 
)
inlineprotectedvirtual

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.
