Constructor Details

BufferedColumnRegionByte

public BufferedColumnRegionByte(@NotNull
 FileDataBufferStore bufferProvider,
 @NotNull
 DeephavenFormatColumnLocation location)

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 Attributes.Values>

Parameters:

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

Returns:

The byte value at the specified element (byte) index

getByte

public byte getByte(@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 Attributes.Values>

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

public byte[] getBytes(long firstElementIndex,
 @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 Attributes.Values>

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

binSearchMatch

public Index binSearchMatch(long firstKey,
 long lastKey,
 @NotNull
 SortPair sortPair,
 @NotNull
 Object[] sortedKeys)

Description copied from interface: ColumnRegion

Given that this column is sorted, match the input keys using a binary search.

Specified by:

binSearchMatch in interface ColumnRegion<ATTR extends Attributes.Values>

Parameters:

firstKey - The first key to search

lastKey - The last key to search

sortPair - the sorting definition

sortedKeys - the keys to search for, in no particular order
