java.lang.Object

org.elasticsearch.index.mapper.blockloader.docvalues.BlockDocValuesReader.DocValuesBlockLoader

org.elasticsearch.index.mapper.blockloader.docvalues.BytesRefsFromBinaryBlockLoader

All Implemented Interfaces:

BlockLoader

public class BytesRefsFromBinaryBlockLoader
extends BlockDocValuesReader.DocValuesBlockLoader

This block loader should be used for fields that are directly encoded as binary values but are always single valued, such as the histogram fields. See also BytesRefsFromCustomBinaryBlockLoader for multivalued binary fields, and BytesRefsFromOrdsBlockLoader for ordinals-based binary values
