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

org.apache.lucene.index.DocsAndPositionsEnum.nextPosition()
Returns the next position. You should only call this up to {@link DocsEnum#freq()} times elsethe behavior is not defined. If positions were not indexed this will return -1; this only happens if offsets were indexed and you passed needsOffset=true when pulling the enum.

              assertEquals(iwDocsAndPos.freq(), memDocsAndPos.freq());
              for (int i = 0; i < iwDocsAndPos.freq(); i++) {
                assertEquals("term: " + iwTermsIter.term().utf8ToString(), iwDocsAndPos.nextPosition(), memDocsAndPos.nextPosition());
