static enum	Nc4Chunking.Strategy

Method Summary

Modifier and Type	Method	Description
long[]	computeChunking(Variable v)	Compute the chunk size for this Variable.
int	getDeflateLevel(Variable v)	Get the deflation level.
boolean	isChunked(Variable v)	Should this variable be chunked?
boolean	isShuffle(Variable v)	Set true to turn shuffling on which may improve compression.

Method Details

isChunked

boolean isChunked(Variable v)

Should this variable be chunked?

computeChunking

long[] computeChunking(Variable v)

Compute the chunk size for this Variable.

getDeflateLevel

int getDeflateLevel(Variable v)

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

isShuffle

boolean isShuffle(Variable v)

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