public class SimpleInstanceFactory

extends InstanceFactory

An instance factory that just passes on information rather than converting it into a different format. The data set information includes the file category set, the data set, and the features. An instance list consists of an array of SparseInstanceBags. An instance is a SparseInstanceBag.
