Examples of org.apache.lucene.util.encoding.UniqueValuesIntEncoder

org.apache.lucene.util.encoding.UniqueValuesIntEncoder
An {@link IntEncoderFilter} which ensures only unique values are encoded. Theimplementation assumes the values given to {@link #encode(int)} are sorted.If this is not the case, you can chain this encoder with {@link SortingIntEncoder}. @lucene.experimental

    encoderTest(new SortingIntEncoder(new UniqueValuesIntEncoder(new DGapIntEncoder(new NOnesIntEncoder(4)))));
  }
  
  @Test
  public void testSortingUniqueDGapNOnes3() {
    encoderTest(new SortingIntEncoder(new UniqueValuesIntEncoder(new DGapIntEncoder(new NOnesIntEncoder(3)))));
  }
