Method Detail

isChunked

public boolean isChunked(Variable v)

Description copied from interface: Nc4Chunking

Should this variable be chunked?

Specified by:

isChunked in interface Nc4Chunking

computeChunking

public long[] computeChunking(Variable v)

Description copied from interface: Nc4Chunking

Compute the chunk size for this Variable.

Specified by:

computeChunking in interface Nc4Chunking

getDeflateLevel

public int getDeflateLevel(Variable v)

Description copied from interface: Nc4Chunking

Get the deflation level. 0 corresponds to no compression and 9 to maximum compression.

Specified by:

getDeflateLevel in interface Nc4Chunking

isShuffle

public boolean isShuffle(Variable v)

Description copied from interface: Nc4Chunking

Set true to turn shuffling on which may improve compression. This option is ignored unless a non-zero deflation level is specified.

Specified by:

isShuffle in interface Nc4Chunking
