TimeSeries

public TimeSeries(java.util.Collection al)

Construct TreeSet from Collection.

TimeSeries

public TimeSeries(java.util.SortedSet ss)

Construct TreeSet from SortedSet.

Method Detail

add

public boolean add(java.lang.Object sa)

Add to the sorted table.

Overrides:

add in class java.util.TreeSet

compare

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

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

Specified by:

compare in interface java.util.Comparator

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.
