Class BlockStoredFieldsReader

java.lang.Object

org.elasticsearch.index.mapper.BlockStoredFieldsReader

All Implemented Interfaces:

BlockLoader.Reader, BlockLoader.RowStrideReader

public abstract class BlockStoredFieldsReader
extends Object
implements BlockLoader.RowStrideReader

Loads values from IndexReader.storedFields(). This whole process is very slow and cast-tastic, so it doesn't really try to avoid megamorphic invocations. It's just going to be slow. Note that this extends BlockDocValuesReader because it pretends to load doc values because, for now, ESQL only knows how to load things in a doc values order.
