Public Member Functions
virtual	~TextQueryRep ()
virtual void	startIteration () const =0
	This, along with hasMore(), nextTerm(), supports iteration over terms.
virtual bool	hasMore () const =0
virtual QueryTerm *	nextTerm () const =0
	Fetch the next term. A new instance is generated; the caller is responsible for deleting it!
virtual double	scoreConstant () const =0
	Any query-specific constant term in the scoring formula.

Member Function Documentation

virtual bool lemur::api::TextQueryRep::hasMore (   )  const [pure virtual]

Implemented in lemur::retrieval::ArrayQueryRep.

virtual QueryTerm* lemur::api::TextQueryRep::nextTerm (   )  const [pure virtual]

Fetch the next term. A new instance is generated; the caller is responsible for deleting it! Implemented in lemur::retrieval::ArrayQueryRep.

virtual double lemur::api::TextQueryRep::scoreConstant (   )  const [pure virtual]

Any query-specific constant term in the scoring formula. Implemented in lemur::retrieval::SimpleKLQueryModel, and lemur::retrieval::ArrayQueryRep.

virtual void lemur::api::TextQueryRep::startIteration (   )  const [pure virtual]

This, along with hasMore(), nextTerm(), supports iteration over terms. Implemented in lemur::retrieval::ArrayQueryRep.
