Modifier and Type	Method	Description
static ColumnRegionLong<DictionaryKeys>	create(RegionedPageStore.Parameters parameters, int regionIndex, @NotNull ColumnRegionObject<?,?> sourceRegion)
void	fillChunkAppend(@NotNull ChunkSource.FillContext context, @NotNull WritableChunk<? super DictionaryKeys> destination, @NotNull RowSequence rowSequence)	Appends the values referenced by orderKeys onto destination.
long	getLong(long elementIndex)	Get a single long from this region.
long	getLong(@NotNull ChunkSource.FillContext context, long elementIndex)	Get a single long from this region.
void	invalidate()	Invalidate the region -- any further reads that cannot be completed consistently and correctly will fail.
long	mask()	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) .

Method Details

create

public static ColumnRegionLong<DictionaryKeys> create(@NotNull
 RegionedPageStore.Parameters parameters,
 int regionIndex,
 @NotNull
 @NotNull ColumnRegionObject<?,?> sourceRegion)

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<DictionaryKeys>

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<DictionaryKeys>

Returns:

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

getLong

public long getLong(long elementIndex)

Description copied from interface: ColumnRegionLong

Get a single long from this region.

Specified by:

getLong in interface ColumnRegionLong<DictionaryKeys>

Parameters:

elementIndex - Element row key in the table's address space

Returns:

The long value at the specified element row key

getLong

public long getLong(@NotNull
 @NotNull ChunkSource.FillContext context,
 long elementIndex)

Description copied from interface: ColumnRegionLong

Get a single long from this region.

Specified by:

getLong in interface ColumnRegionLong<DictionaryKeys>

Parameters:

context - A PagingContextHolder to enable resource caching where suitable, with current region index pointing to this region

elementIndex - Element row key in the table's address space

Returns:

The long value at the specified element row key

fillChunkAppend

public void fillChunkAppend(@NotNull
 @NotNull ChunkSource.FillContext context,
 @NotNull
 @NotNull WritableChunk<? super DictionaryKeys> 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<DictionaryKeys>
