| ↳ | java.beans.PropertyChangeSupport |
Manages a list of listeners to be notified when a property changes. Listeners subscribe to be notified of all property changes, or of changes to a single named property.
This class is thread safe. No locking is necessary when subscribing or unsubscribing listeners, or when publishing events. Callers should be careful when publishing events because listeners may not be thread safe.
