PropertyChangeSupport.GetPropertyChangeListeners Method

Definition

Namespace:

Java.Beans

Assembly:

Mono.Android.dll

Overloads

GetPropertyChangeListeners()	Returns an array of all the listeners that were added to the PropertyChangeSupport object with addPropertyChangeListener().
GetPropertyChangeListeners(String)	Returns an array of all the listeners which have been associated with the named property.

GetPropertyChangeListeners()

Returns an array of all the listeners that were added to the PropertyChangeSupport object with addPropertyChangeListener().

[Android.Runtime.Register("getPropertyChangeListeners", "()[Ljava/beans/PropertyChangeListener;", "GetGetPropertyChangeListenersHandler")]
public virtual Java.Beans.IPropertyChangeListener[]? GetPropertyChangeListeners ();

[<Android.Runtime.Register("getPropertyChangeListeners", "()[Ljava/beans/PropertyChangeListener;", "GetGetPropertyChangeListenersHandler")>]
abstract member GetPropertyChangeListeners : unit -> Java.Beans.IPropertyChangeListener[]
override this.GetPropertyChangeListeners : unit -> Java.Beans.IPropertyChangeListener[]

Returns

IPropertyChangeListener[]

all of the PropertyChangeListeners added or an empty array if no listeners have been added

Attributes

RegisterAttribute

Remarks

Returns an array of all the listeners that were added to the PropertyChangeSupport object with addPropertyChangeListener().

If some listeners have been added with a named property, then the returned array will be a mixture of PropertyChangeListeners and PropertyChangeListenerProxys. If the calling method is interested in distinguishing the listeners then it must test each element to see if it's a PropertyChangeListenerProxy, perform the cast, and examine the parameter.

{@code
            PropertyChangeListener[] listeners = bean.getPropertyChangeListeners();
            for (int i = 0; i < listeners.length; i++) {
              if (listeners[i] instanceof PropertyChangeListenerProxy) {
                PropertyChangeListenerProxy proxy =
                               (PropertyChangeListenerProxy)listeners[i];
                if (proxy.getPropertyName().equals("foo")) {
                  // proxy is a PropertyChangeListener which was associated
                  // with the property named "foo"
                }
              }
            }
            }
