All Implemented Interfaces:

Serializable, Constraint, DataObject, PropertyChangeNotifier

Direct Known Subclasses:

CardinalityDeviceConstraint

public class IntervalConstraint
extends DefaultConstraint

This class represents an interval constraint. All gestures must be performed within a certain time interval. It does not matter in which order and how they are related in time (e.g. sequential, concurrent or a mix).

Method Detail

setDuration

public void setDuration(String time)
                 throws ParseException

Set the duration of the interval.

Parameters:

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

Throws:

ParseException - thrown if the duration could not be parsed

getDuration

public Calendar getDuration()

Get the duration of the interval

determineTimeWindows

public Map<String,Calendar> determineTimeWindows()

Description copied from interface: Constraint

Determine the time window for each composing gesture.

Specified by:

determineTimeWindows in interface Constraint

Specified by:

Returns:

Mapping between the gesture name and the corresponding time window.

generatePatterns

public Set<String> generatePatterns(Map<String,String> charMapping)

Description copied from interface: Constraint

Generate all possible string patterns that represent the composite gesture.

Specified by:

generatePatterns in interface Constraint

Specified by:

generatePatterns in class DefaultConstraint

Parameters:

charMapping - Mapping between the gesture class name and the character representation

validateConditions

public boolean validateConditions(List<Gesture<?>> gestures,
                                  IDeviceManager manager)

Description copied from interface: Constraint

Validate the constraint conditions.

Specified by:

validateConditions in interface Constraint

Overrides:

validateConditions in class DefaultConstraint
