Method Detail

rank

public int rank()

Description copied from interface: QDataSet

returns the rank of the dataset, which is the number of indeces used to access data. Only rank 1, 2, and 3 datasets are supported in the interface. When a dataset's rank is 4 or greater, it should implement the HighRankDataSet interface which affords a slice operation to reduce rank. When a dataset's rank is 0, it should implement the RankZeroDataSet interface, which has a no-argument accessor. (TODO: Note that rank 0 and rank N have very limited use, so many routines aren't coded to handle them.)
