Method Details

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

fillChunkAppend

public void fillChunkAppend(@NotNull
 @NotNull ChunkSource.FillContext context,
 @NotNull
 @NotNull WritableChunk<? super ATTR> destination,
 int length)

Description copied from interface: Page.WithDefaultsForRepeatingValues

Appends the values repeating value length times to destination.

Specified by:

fillChunkAppend in interface Page.WithDefaultsForRepeatingValues<ATTR extends Any>

getBytes

public byte[] getBytes(long firstElementIndex,
 @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:

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
