Constructor & Destructor Documentation

lemur::retrieval::ArrayQueryRep::ArrayQueryRep (  int  size  )  [inline]

The size passed in must be large enough to hold all the terms.

lemur::retrieval::ArrayQueryRep::ArrayQueryRep (  int  size, const lemur::api::TermQuery &  qry, const lemur::api::Index &  dbIndex )

The size passed in must be large enough to hold all the terms, typically dbIndex.termCountUnique()+1.

lemur::retrieval::ArrayQueryRep::ArrayQueryRep (  int  size, const lemur::utility::FreqVector &  qryVec )

build a query rep with a frequency vector

Member Function Documentation

virtual bool lemur::retrieval::ArrayQueryRep::hasMore (   )  const [inline, virtual]

Implements lemur::api::TextQueryRep.

virtual void lemur::retrieval::ArrayQueryRep::incCount (  lemur::api::TERMID_T  wdIndex, double  count )  [inline, virtual]

virtual lemur::api::QueryTerm* lemur::retrieval::ArrayQueryRep::makeQueryTerm (  lemur::api::TERMID_T  wdIndex, double  wdCount )  const [inline, protected, virtual]

Reimplemented in lemur::retrieval::OkapiQueryRep.

lemur::api::QueryTerm * lemur::retrieval::ArrayQueryRep::nextTerm (   )  const [virtual]

Fetch the next term. A new instance is generated; the caller is responsible for deleting it! Implements lemur::api::TextQueryRep.

virtual double lemur::retrieval::ArrayQueryRep::scoreConstant (   )  const [inline, virtual]

Any query-specific constant term in the scoring formula. Implements lemur::api::TextQueryRep. Reimplemented in lemur::retrieval::SimpleKLQueryModel.

virtual void lemur::retrieval::ArrayQueryRep::setCount (  lemur::api::TERMID_T  wdIndex, double  count )  [inline, virtual]

virtual void lemur::retrieval::ArrayQueryRep::setScoreConstant (  double  scoreConst  )  [inline, virtual]

virtual void lemur::retrieval::ArrayQueryRep::startIteration (   )  const [inline, virtual]

This, along with hasMore(), nextTerm(), supports iteration over terms. Implements lemur::api::TextQueryRep.

virtual double lemur::retrieval::ArrayQueryRep::totalCount (   )  const [inline, virtual]
