Remarks

This is a utility class that can be used by beans that support bound properties. It manages a list of listeners and dispatches PropertyChangeEvents to them. You can use an instance of this class as a member field of your bean and delegate these types of work to it. The PropertyChangeListener can be registered for all properties or for a property specified by name.

Here is an example of PropertyChangeSupport usage that follows the rules and recommendations laid out in the JavaBeans™ specification:

public class MyBean {
                private final PropertyChangeSupport pcs = new PropertyChangeSupport(this);

                public void addPropertyChangeListener(PropertyChangeListener listener) {
                    this.pcs.addPropertyChangeListener(listener);
                }

                public void removePropertyChangeListener(PropertyChangeListener listener) {
                    this.pcs.removePropertyChangeListener(listener);
                }

                private String value;

                public String getValue() {
                    return this.value;
                }

                public void setValue(String newValue) {
                    String oldValue = this.value;
                    this.value = newValue;
                    this.pcs.firePropertyChange("value", oldValue, newValue);
                }

                [...]
            }

A PropertyChangeSupport instance is thread-safe.

This class is serializable. When it is serialized it will save (and restore) any listeners that are themselves serializable. Any non-serializable listeners will be skipped during serialization.
