virtual ~Parser ()
virtual void parse (char *filename)
virtual void parseFile (char *filename)=0

 return the byte position at the beginning of the current document

Member Function Documentation

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 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 char *    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 char *    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 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
