public class DataList

extends java.util.Vector

implements RecordStreamListener, Subsettable, AssignableSubset, java.io.Serializable

Early version of a class that stores arbitrary records in a list, that is row-wise, in contrast to a DataFrame that stores variables (that is columnwise). This supports notification from a stream source which provides each record and an object of this class can process the record before storing it or simply discard it.
