getLocation

public DeephavenFormatColumnLocation getLocation()

Specified by:

getLocation in interface ColumnRegion<ATTR extends Attributes.Values>

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

makeFillContext

public ChunkSource.FillContext makeFillContext(int chunkCapacity,
 SharedContext sharedContext)

Description copied from interface: FillContextMaker

Allocate a new ChunkSource.FillContext for filling chunks from this FillContextMaker, typically a ChunkSource.

Specified by:

makeFillContext in interface DefaultChunkSource<ATTR extends Attributes.Values>

Specified by:

makeFillContext in interface FillContextMaker

Parameters:

chunkCapacity - The maximum size of any WritableChunk that will be filled with this context

sharedContext - Shared store of intermediate results.

Returns:

A context for use with fill operations

couldInclude

public boolean couldInclude(@NotNull
 Object[] sortedKeys)

Description copied from interface: ColumnRegion

Check if the region could possibly include any of the keys we're searching for

Specified by:

couldInclude in interface ColumnRegion<ATTR extends Attributes.Values>

Parameters:

sortedKeys - the keys to search for

Returns:

true if the region possibly contains the values

chunkMatch

public Index chunkMatch(long regionFirstKey,
 @NotNull
 OrderedKeys keysToFilter,
 boolean caseInsensitive,
 boolean invertMatch,
 @NotNull
 Object[] sortedKeys)

Specified by:

chunkMatch in interface ColumnRegion<ATTR extends Attributes.Values>
