Method Details

getByte

byte getByte(long elementIndex)

Get a single byte from this region.

Parameters:

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

Returns:

The byte value at the specified element row key

getByte

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

Get a single byte from this region.

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

byte[] getBytes(long firstElementIndex,
 @NotNull
 @org.jetbrains.annotations.NotNull byte[] destination,
 int destinationOffset,
 int length)

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

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

getChunkType

@FinalDefault
default ChunkType getChunkType()

Description copied from interface: ChunkSource

Get the most suitable ChunkType for use with this ChunkSource.

Specified by:

getChunkType in interface ChunkSource<ATTR extends Any>

Returns:

The ChunkType

createNull

static <ATTR extends Any> ColumnRegionByte<ATTR> createNull(long pageMask)
