Class FeatureFactory

  +--edu.berkeley.guir.lib.gesture.FeatureFactory

public class FeatureFactory

extends Object

Keeps a cache of features for GestureObject. Known issues: * Only supports Gesture. * Once a Gesture is added, it will never be garbage collected. FeatureFactory could use a WeakHashMap instead of a Hashtable, but that wouldn't help since each value (Feature) has a strong reference to its Gesture.
