Class BytesRefsFromBinaryBlockLoader

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

BytesRefsFromBinaryBlockLoader

public BytesRefsFromBinaryBlockLoader(org.apache.lucene.util.IOFunction<org.apache.lucene.index.LeafReaderContext,org.apache.lucene.index.BinaryDocValues> docValuesSupplier)

Create a block loader from a BinaryDocValues supplier. This is useful when the doc values are not directly stored in a single field but are composed of multiple sources, as is the case for Pattern Text.

Method Details

builder

public BlockLoader.Builder builder(BlockLoader.BlockFactory factory,
 int expectedCount)

Description copied from interface: BlockLoader

The BlockLoader.Builder for data of this type. Called when loading from a multi-segment or unsorted block.

reader

 org.apache.lucene.index.LeafReaderContext context)
                                       throws IOException

Specified by:

reader in class BlockDocValuesReader.DocValuesBlockLoader

Throws:

IOException
