Public Methods

 ArrayQueryRep (int size)
 The size passed in must be large enough to hold all the terms.

 ArrayQueryRep (int size, const TermQuery &qry, const Index &dbIndex)
 The size passed in must be large enough to hold all the terms, typically dbIndex.termCountUnique()+1.

 ArrayQueryRep (int size, const FreqVector &qryVec)
 build a query rep with a frequency vector

virtual ~ArrayQueryRep ()
virtual void startIteration () const
 This, along with hasMore(), nextTerm(), supports iteration over terms.

virtual bool hasMore () const
virtual QueryTerm * nextTerm () const
 Fetch the next term. A new instance is generated; the caller is responsible for deleting it!

virtual void incCount (TERMID_T wdIndex, double count)
virtual void setCount (TERMID_T wdIndex, double count)
virtual double totalCount () const
virtual double scoreConstant () const
 Any query-specific constant term in the scoring formula.

virtual void setScoreConstant (double scoreConst)

Protected Methods

virtual QueryTerm * makeQueryTerm (TERMID_T wdIndex, double wdCount) const
