Method Details

makeFillContext

public final ArrowWrapperTools.FillContext makeFillContext(int chunkCapacity,
 SharedContext sharedContext)

Description copied from interface: FillContextMaker

Allocate a new ChunkSource.FillContext for filling chunks from this FillContextMaker, typically a ChunkSource.

Parameters:

chunkCapacity - The maximum size of any WritableChunk that will be filled with this context

sharedContext - Shared store of intermediate results.

Returns:

A context for use with fill operations

fillChunk

 ArrowWrapperTools.FillContext context,
 @NotNull
 @NotNull RowSequence rowSequence,
 @NotNull
 @NotNull LongConsumer rowKeyConsumer)

getBlockNo

protected final int getBlockNo(long rowKey)

getPositionInBlock

protected final int getPositionInBlock(long rowKey)
