org.das2.qds.IndexListDataSetIterator

Iterator that uses a rank 2 list of indeces. For example, to iterate over 10 points of a rank 2 dataset, this would be constructed with a dataset[10,2].

IndexListDataSetIterator( QDataSet indeces )

Create the iterator

createEmptyDs

createEmptyDs( ) → org.das2.qds.DDataSet

Returns:
