All Implemented Interfaces:

Serializable, Constraint, DataObject, PropertyChangeNotifier

Direct Known Subclasses:

ProximitySequenceConstraint

public class SequenceConstraint
extends DefaultConstraint

This class represents a sequence constraint. All gestures have to be performed in the order they were defined. A minimum and a maximum time interval between two consecutive gestures has to be defined.

                throws ParseException

Set the minimum time between two gestures

Parameters:

time - minimum time in format "hh:mm:ss.SSS"

Throws:

ParseException - thrown if the minimum time could not be parsed

setMaxTime

public void setMaxTime(String time)
                throws ParseException

Set the maximum time between two gestures

Parameters:

time - maximum time in format "hh:mm:ss.SSS"

Throws:

ParseException - thrown if the maximum time could not be parsed

getMinTime

public Calendar getMinTime()

Get the minimum time between two gestures

getMaxTime

public Calendar getMaxTime()

Get the maximum time between two gestures
