Class TimeSeries

java.lang.Object
  edu.unh.sdb.datasource.TimeSeries

public class TimeSeries
extends java.lang.Object

This class encapsulates time series data without imposing a particular data access interface on the series itself. It is primarily intended to support the TimeSeriesDataSource, but we thought there might be some advantage to provide a class to manage the members of the series without imposing the DataSource interface onto the manager. For now, we'll try to define the series as a series of DataCollections.
