 @NotNull
 @NotNull ColumnRegionByte<ATTR>[] regions,
 @NotNull
 @NotNull ColumnLocation columnLocation)

Method Details

getColumnLocation

public Optional<ColumnLocation> getColumnLocation()

Specified by:

getColumnLocation in interface ColumnRegion<ATTR extends Any>

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>

getByte

public byte getByte(long elementIndex)

Description copied from interface: ColumnRegionByte

Get a single byte from this region.

Specified by:

getByte in interface ColumnRegionByte<ATTR extends Any>

Parameters:

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

Returns:

The byte value at the specified element row key

getByte

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

Description copied from interface: ColumnRegionByte

Get a single byte from this region.

Specified by:

getByte in interface ColumnRegionByte<ATTR extends Any>

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 byte value at the specified element row ket

getBytes

public byte[] getBytes(long firstElementIndex,
 byte[] destination,
 int destinationOffset,
 int length)

Description copied from interface: ColumnRegionByte

Get a range of bytes from this region. Implementations are not required to verify that the range specified is meaningful.

Specified by:

getBytes in interface ColumnRegionByte<ATTR extends Any>

Parameters:

firstElementIndex - First element row keyt in the table's address space

destination - Array to store results

destinationOffset - Offset into destination to begin storing at

length - Number of bytes to get

Returns:

destination, to enable method chaining

supportedActions

public List<RegionedPushdownAction> supportedActions()

Description copied from interface: RegionedPushdownFilterMatcher

Get the list of pushdown actions supported by this matcher. Defaults to an empty list.

Specified by:

supportedActions in interface RegionedPushdownFilterMatcher

estimatePushdownAction

public long estimatePushdownAction(RegionedPushdownAction action,
 WhereFilter filter,
 RowSet selection,
 boolean usePrev,
 PushdownFilterContext filterContext,
 RegionedPushdownAction.EstimateContext estimateContext)

Description copied from interface: RegionedPushdownFilterMatcher

Estimate the cost of the given pushdown action. Returns Long.MAX_VALUE if the action is not supported by this matcher.

Specified by:

estimatePushdownAction in interface RegionedPushdownFilterMatcher

performPushdownAction

public PushdownResult performPushdownAction(RegionedPushdownAction action,
 WhereFilter filter,
 RowSet selection,
 PushdownResult input,
 boolean usePrev,
 PushdownFilterContext filterContext,
 RegionedPushdownAction.ActionContext actionContext)

Description copied from interface: RegionedPushdownFilterMatcher

Perform the pushdown action for the given filter and filter context.

Specified by:

performPushdownAction in interface RegionedPushdownFilterMatcher
