## 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 Matcher& reflex::AbstractLexer< M >::Matcher::operator= | ( | const Matcher & | matcher | ) |

inline virtual

Assign a matcher, the underlying pattern object is shared (not deep copied).

template<typename M >

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

inline protected virtual

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.

## Member Data Documentation
