Class org.apache.lucene.index.TermPositions

Examples of org.apache.lucene.index.TermPositions.nextPosition()

org.apache.lucene.index.TermPositions.nextPosition()
Returns next position in the current document. It is an error to call this more than {@link #freq()} timeswithout calling {@link #next()}
This is invalid until {@link #next()} is called forthe first time.

    termPositions.seek(new Term("preanalyzed", "term3"));

    assertEquals(1, termPositions.freq());
    assertEquals(2, termPositions.nextPosition());
    reader.close();
    
    // 3) reset stream and consume tokens again
    stream.reset();
