Constructor Details

AppendOnlyFixedSizePageRegionByte

public AppendOnlyFixedSizePageRegionByte(long pageMask,
 int pageSize,
 @NotNull
 @NotNull AppendOnlyRegionAccessor<ATTR> accessor)

Method Details

getByte

public byte getByte(long rowKey)

Description copied from interface: ColumnRegionByte

Get a single byte from this region.

Specified by:

getByte in interface ColumnRegionByte<ATTR extends Any>

Parameters:

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

Returns:

The byte value at the specified element row key

getBytes

public byte[] getBytes(long firstRowKey,
 @NotNull
 @org.jetbrains.annotations.NotNull 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:

firstRowKey - 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

getPageContaining

@NotNull
public final @NotNull ChunkHolderPageByte<ATTR> getPageContaining(@Nullable
 @Nullable ChunkSource.FillContext fillContext,
 long rowKey)

Specified by:

getPageContaining in interface PageStore<ATTR extends Any,ATTR extends Any,ChunkHolderPageByte<ATTR extends Any>>

Parameters:

fillContext - The fill context to use; may be null if the calling code does not have a fill context

rowKey - The row key to get the page for

Returns:

The page containing rowKey, after applying PagingChunkSource.mask().
