ColumnRegionReferencingImpl

public ColumnRegionReferencingImpl(@NotNull
 REFERENCED_COLUMN_REGION referencedColumnRegion)

Method Details

invalidate

public void invalidate()

Description copied from interface: ColumnRegion

Invalidate the region -- any further reads that cannot be completed consistently and correctly will fail.

Specified by:

invalidate in interface ColumnRegion<ATTR extends Any>

getReferencedRegion

@NotNull
public REFERENCED_COLUMN_REGION getReferencedRegion()

Specified by:

getReferencedRegion in interface ColumnRegionReferencing<ATTR extends Any,REFERENCED_COLUMN_REGION extends ColumnRegion<ATTR>>

mask

public long mask()

Description copied from interface: PagingChunkSource

This mask is applied to RowSequences which are passed into DefaultChunkSource.getChunk(io.deephaven.engine.table.ChunkSource.GetContext, io.deephaven.engine.rowset.RowSequence), ChunkSource.fillChunk(io.deephaven.engine.table.ChunkSource.FillContext, io.deephaven.chunk.WritableChunk<? super ATTR>, io.deephaven.engine.rowset.RowSequence), and PagingChunkSource.fillChunkAppend(FillContext, WritableChunk, RowSequence.Iterator) . This allows PagingChunkSources to be cached and reused even if they are properly relocated in key space.

Specified by:

mask in interface PagingChunkSource<ATTR extends Any>

Returns:

The mask for this PagingChunkSource, which must be a bitmask representing some number of lower order bits of a long.

fillChunkAppend

public void fillChunkAppend(@NotNull
 ChunkSource.FillContext context,
 @NotNull
 @NotNull WritableChunk<? super ATTR> destination,
 @NotNull
 @NotNull RowSequence rowSequence)

Description copied from interface: Page.WithDefaults

Appends the values referenced by orderKeys onto destination. orderKeys are assumed to be entirely contained on this Page.

Specified by:

fillChunkAppend in interface Page.WithDefaults<ATTR extends Any>

releaseCachedResources

@OverridingMethodsMustInvokeSuper
public void releaseCachedResources()

Description copied from interface: Releasable

Release any resources held for caching purposes. Implementations need not guarantee that they are safe for normal use concurrently with invocations of this method.

Specified by:

releaseCachedResources in interface Releasable
