columnAtATimeReader

public final BlockLoader.ColumnAtATimeReader columnAtATimeReader(org.apache.lucene.index.LeafReaderContext context)

Description copied from interface: BlockLoader

Build a column-at-a-time reader. May return null if the underlying storage needs to be loaded row-by-row. Callers should try this first, only falling back to BlockLoader.rowStrideReader(org.apache.lucene.index.LeafReaderContext) if this returns null or if they can't load column-at-a-time themselves.

Specified by:

columnAtATimeReader in interface BlockLoader

rowStrideStoredFieldSpec

public final StoredFieldsSpec rowStrideStoredFieldSpec()

Description copied from interface: BlockLoader

What stored fields are needed by this reader.

Specified by:

rowStrideStoredFieldSpec in interface BlockLoader

supportsOrdinals

public final boolean supportsOrdinals()

Description copied from interface: BlockLoader

Does this loader support loading bytes via calling BlockLoader.ordinals(org.apache.lucene.index.LeafReaderContext).

Specified by:

supportsOrdinals in interface BlockLoader

ordinals

public final org.apache.lucene.index.SortedSetDocValues ordinals(org.apache.lucene.index.LeafReaderContext context)

Description copied from interface: BlockLoader

Load ordinals for the provided context.

Specified by:

ordinals in interface BlockLoader
