org.das2.qds.CdfSparseDataSet

dataset for modeling when data values repeat. Instead of storing copies of the data, the get method looks up the index. For example: 

 ds= CdfSparseDataSet(1,200,dataset(1))
 ds.putValues( 10, dataset(2) )
 ds.putValues( 110, dataset(3) )
 plot( ds )

CdfSparseDataSet( int rank, int length, QDataSet value )

create the DataSet with the given length.

datasetCount

datasetCount( ) → int

return the number of different datasets.

Returns:

the number of different datasets.
