Method Details

binaryValue

public org.apache.lucene.util.BytesRef binaryValue()

Encodes the collection of binary doc values as a single contiguous binary array, wrapped in BytesRef. This array takes the form of [doc value count][length of value 1][value 1][length of value 2][value 2]...

Specified by:

binaryValue in interface org.apache.lucene.index.IndexableField

Specified by:

binaryValue in class MultiValuedBinaryDocValuesField

encode

public static org.apache.lucene.util.BytesRef encode(List<org.apache.lucene.util.BytesRef> values)

Encodes a list of BytesRef values into the integrated-count format: [count][len1][val1][len2][val2]....

Note, this is basically the static version of binaryValue(). The benefit of having this static code is that we can skip the overhead of creating a whole new Lucene field and adding values to it.
