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.
