Java Source Code / Java Documentation » Net » lucene connector » org.apache.lucene.search   Source Cross Reference   Class Diagram   Java Document (Java Doc)   java.lang.Object    org.apache.lucene.search.Scorer       org.apache.lucene.search.TermScorer TermScorer final class TermScorer extends Scorer (Code) Expert: A Scorer for documents matching a Term. Constructor Summary   TermScorer(Weight weight, TermDocs td, Similarity similarity, byte[] norms)      Construct a TermScorer. Method Summary public  int doc()      Returns the current document number matching the query. public  Explanation explain(int doc)      Returns an explanation of the score for a document. public  boolean next()      Advances to the next document matching the query. public  void score(HitCollector hc)      protected  boolean score(HitCollector c, int end)      public  float score()      public  boolean skipTo(int target)      Skips to the first match beyond the current whose document number is greater than or equal to a given target. public  String toString()      Returns a string representation of this TermScorer. Constructor Detail TermScorer TermScorer(Weight weight, TermDocs td, Similarity similarity, byte[] norms)(Code) Construct a TermScorer. Parameters:   weight - The weight of the Term in the query. Parameters:   td - An iterator over the documents matching the Term. Parameters:   similarity - The Similarity implementation to be used for score computations. Parameters:   norms - The field norms of the document fields for the Term. Method Detail doc public int doc()(Code) Returns the current document number matching the query. Initially invalid, until TermScorer.next() is called the first time. explain public Explanation explain(int doc) throws IOException(Code) Returns an explanation of the score for a document. When this method is used, the TermScorer.next() method and the TermScorer.score(HitCollector) method should not be used. Parameters:   doc - The document number for the explanation. next public boolean next() throws IOException(Code) Advances to the next document matching the query. The iterator over the matching documents is buffered using TermDocs.read(int[]int[]) . true iff there is another document matching the query. score public void score(HitCollector hc) throws IOException(Code) score protected boolean score(HitCollector c, int end) throws IOException(Code) score public float score()(Code) skipTo public boolean skipTo(int target) throws IOException(Code) Skips to the first match beyond the current whose document number is greater than or equal to a given target. The implementation uses TermDocs.skipTo(int) . Parameters:   target - The target document number. true iff there is such a match. toString public String toString()(Code) Returns a string representation of this TermScorer.
