public interface Timeseries

A client-side handle to a timeseries inside the Smart Database. Manipulation of this object on the client results in data being stored and retrieved in database.

Method Summary

java.util.Date	getDate(int n) Gets date of the nth point
int	getDelta() Number of milliseconds between measurements; zero if irregular timeseries.
java.util.Date	getFirst() Timestamp of first datapoint in timeseries
java.util.Date	getLast() Timestamp of last datapoint in timesries
int	getNumPoints() # of datapoints in timeseries
TimeseriesSpec	getSpec() Description of what this timeseries records
