Detailed Description

Provides a generic parser interface. Assumes that the parser uses an acronym list. If, when developing your parser, you do not use an acronym list, you can just provide an empty implementation of the setAcroList function.

Member Function Documentation

void Parser::clearAcros (    )  [protected]

clears internal acronym list

virtual long Parser::fileTell (    )  [pure virtual]

return the current byte position of the file being parsed Implemented in ArabicParser, BrillPOSParser, ChineseCharParser, ChineseParser, IdentifinderParser, InqArabicParser, InQueryOpParser, ReutersParser, TrecParser, and WebParser.

virtual long Parser::getDocBytePos (    )  [inline, virtual]

return the byte position at the beginning of the current document

bool Parser::isAcronym (  const char *    word )  [protected]

Checks to see if the word is in the acronym list. Returns false if the list is not set.

virtual void Parser::parse (  const string &    filename )  [inline, virtual]

Parse a file. use parseFile. this method will be deprecated in future

virtual void Parser::parseBuffer (  char *    buf, int    len )  [pure virtual]

Parse a buffer. Implemented in ArabicParser, BrillPOSParser, ChineseCharParser, ChineseParser, IdentifinderParser, InqArabicParser, InQueryOpParser, ReutersParser, TrecParser, and WebParser.

virtual void Parser::parseFile (  const string &    filename )  [pure virtual]

Parse a file. Implemented in ArabicParser, BrillPOSParser, ChineseCharParser, ChineseParser, IdentifinderParser, InqArabicParser, InQueryOpParser, ReutersParser, TrecParser, and WebParser.

void Parser::setAcroList (  string    filename )  [virtual]

Set the acronym list from this file.

void Parser::setAcroList (  const WordSet *    acronyms )  [virtual]

Set the acronym list. Can be an empty implementation if the parser is not designed to deal with acronyms by using a list. WordSet still belongs to the caller
