Method Details

getByte

byte getByte(long elementIndex)

Get a single byte from this region.

Parameters:

elementIndex - Element (byte) index in the table's address space

Returns:

The byte value at the specified element (byte) index

getByte

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

Get a single byte from this region.

Parameters:

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

elementIndex - Element (byte) index in the table's address space

Returns:

The byte value at the specified element (byte) index

getBytes

byte[] getBytes(long firstElementIndex, @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 (byte) index 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

getNativeType

default Class<?> getNativeType()

Specified by:

getNativeType in interface ChunkSource<ATTR extends Attributes.Any>

createNull

static <ATTR extends Attributes.Any> ColumnRegionByte.Null<ATTR> createNull()
