public int getSize()

Get the number of Timestamp in the set.

add

public void add(Timestamp t)

Add a Timestamp to the set.

Parameters:

t - Timestamp to be added.

setTolerance

public void setTolerance(TimeDuration tolerance)

Set the TimeDuration used to define the minimum duration of generated TimeInterval.

Parameters:

tolerance - TimeDuration minimal duration

toIntervalsList

public IntervalsList toIntervalsList()
