public class TimeSeries

extends OrderedList

implements java.io.Serializable

This table will hold a list of timeSeries objects used to predict load via simple curve fit/extrapolation algorithms. This research is funded by DARPA/ITO Contract Number: F30602-98-C-0230 supported by the Air Force Research Laboratory/IF.

Constructor Detail

TimeSeries

public TimeSeries()

Construct empty TreeSet.

Method Detail

add

public boolean add(java.lang.Object sa)

Add to the sorted table.

Overrides:

add in class OrderedList

compare

public int compare(java.lang.Object o1,
                   java.lang.Object o2)

This is required to keep the time samples sorted by time.

Overrides:

compare in class OrderedList

nextValue

public double nextValue(long t)

Compute the value at a given time based on the current samples.

Parameters:

t - The time for which we want to compute the value.

Returns:

The next predicted value at the give time.

dropSample

public void dropSample()

Drop the oldest sample.
