Detailed Description

template<typename E>
class grammar_to_parser::basic_pattern_parser< E >

Parse of pattern defined as string in constructor

---

Member Enumeration Documentation

template<typename E> enum grammar_to_parser::basic_pattern_parser::comparison_type [protected]

Defines how pattern string will be compared with input buffer. Enumeration values: IGNORE_SPACE  White characters will be ignored in input. IGNORE_CASE  Case insensitive compare.

---

Constructor & Destructor Documentation

template<typename E> grammar_to_parser::basic_pattern_parser< E >::basic_pattern_parser (  const std::basic_string< E > &  pattern, int  comparison_type = IGNORE_CASE | IGNORE_SPACE )  [inline]

Constructor with definition of pattern as string parameter Parameters: pattern  string pattern to be searched in input buffer during parsing comparison_type  specifies how string will be compared with input buffer

---

Member Function Documentation

template<typename E> std::basic_istream< E > & grammar_to_parser::basic_pattern_parser< E >::parse (  std::basic_istream< E > &  is  )  [virtual]

The method succeedes if input is same as pattern passed to constructor Implements grammar_to_parser::basic_parser< E >.

template<typename E> unsigned long grammar_to_parser::basic_pattern_parser< E >::parse (  const E *  buf, const unsigned long  buf_length )  [virtual]

The method compares the pattern, passed as constructor parameter, with string stored in input buffer. Parameters: *buf  the buffer containing input string buf_length  the length of buffer Returns: the size of parsed string, if succesfullt, otherwise zero Implements grammar_to_parser::basic_parser< E >.
