    Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans™ has been added to the java.beans package. Please see XMLEncoder.

method:getListeners(java.lang.Class) [NONE]

  • getListeners

    public <T extends EventListener> T[] getListeners​(Class<T> listenerType)
    Returns an array of all the objects currently registered as FooListeners upon this model. FooListeners are registered using the addFooListener method.

    You can specify the listenerType argument with a class literal, such as FooListener.class. For example, you can query a DefaultButtonModel instance m for its action listeners with the following code:

    ActionListener[] als = (ActionListener[])(m.getListeners(ActionListener.class));
    If no such listeners exist, this method returns an empty array.

    Type Parameters:
    T - the type of requested listeners
    Parameters:
    listenerType - the type of listeners requested; this parameter should specify an interface that descends from java.util.EventListener
    Returns:
    an array of all objects registered as FooListeners on this model, or an empty array if no such listeners have been added
    Throws:
    ClassCastException - if listenerType doesn't specify a class or interface that implements java.util.EventListener
    Since:
    1.3

    getActionListeners(), getChangeListeners(), getItemListeners()
