Method Detail

compressAsNotNullable

IChunk<K> compressAsNotNullable(IRowMapping mapping,
                                int[] arrayMapping,
                                int newChunkSize,
                                IChunkFactory<K> defaultChunkCreator)

Compresses the chunk knowing there are not any null in the chunk.

Parameters:

mapping - the mapping from the rows of this chunk to those of the compressed chunk (or null if we compress all rows)

arrayMapping - the array representation of the mapping (or null if we compress all rows)

newChunkSize - the size of the chunk we want to create

defaultChunkCreator - the chunk creator for a "normal" chunk (if this chunks knows of a better way to sparse itself, it can use it)

Returns:

the compressed chunk

destroyNullFlags

Runnable destroyNullFlags()

Returns the runnable to run to destroy the nullable flags.

Returns:

the runnable to run to destroy the nullable flags
