encodeOffsetArray

protected static org.apache.lucene.util.BytesRef encodeOffsetArray(FieldArrayContext.Offsets offset)
                                                            throws IOException

Encodes per-array offsets (in document parsing order) recording which distinct value occupies each slot in a recorded array.

The array takes the form [slot count][ordinal 0][ordinal 1]..., where slot count is the number of leaf positions (one per indexed array element, including nulls) and each following ordinal is either a non-negative index into the per-document sorted set of array values, or -1 when that slot is null. Decoding uses parseOffsetArray(org.elasticsearch.common.io.stream.StreamInput).

Throws:

IOException
