## Class AbstractDropTarget

- java.lang.Object
- - javax.faces.component.UIComponent
  - - javax.faces.component.UIComponentBase
    - - org.richfaces.component.AbstractDropTarget

- All Implemented Interfaces:
    EventListener, javax.faces.component.PartialStateHolder, javax.faces.component.StateHolder, javax.faces.component.TransientStateHolder, javax.faces.event.ComponentSystemEventListener, javax.faces.event.FacesListener, javax.faces.event.SystemEventListenerHolder, AjaxActivatorProps, AjaxProps, BypassProps, ImmediateProps
  Direct Known Subclasses:
    UIDropTarget

      public abstract class AbstractDropTarget
      extends javax.faces.component.UIComponentBase
      implements AjaxProps, BypassProps, ImmediateProps

  The <rich:dropTarget> component can be added to a component so that the component can accept dragged items. The dragged items must be defined with a compatible drop type for the <rich:dragSource> component.

  - ### Constructor Detail

    - #### AbstractDropTarget

          public AbstractDropTarget()

  - ### Method Detail

    - #### getDropValue

          public abstract Object getDropValue()

      Data to be processed after a drop event

    - #### getAcceptedTypes

          public abstract Object getAcceptedTypes()

      A list of drag zones types, which elements are accepted by a drop zone

    - #### getDropListener

          public abstract javax.el.MethodExpression getDropListener()

      MethodExpression representing an action listener method that will be notified after drop operation. The expression must evaluate to a public method that takes an DropEvent parameter, with a return type of void, or to a public method that takes no arguments with a return type of void. In the latter case, the method has no way of easily knowing where the event came from, but this can be useful in cases where a notification is needed that "some action happened".

    - #### addDropListener

          public void addDropListener(DropListener listener)

    - #### getDropListeners

          public DropListener[] getDropListeners()

    - #### removeDropListener

          public void removeDropListener(DropListener listener)

    - #### queueEvent

          public void queueEvent(javax.faces.event.FacesEvent event)

      Overrides:
        `queueEvent` in class `javax.faces.component.UIComponentBase`

    - #### broadcast

          public void broadcast(javax.faces.event.FacesEvent event)
                         throws javax.faces.event.AbortProcessingException

      Overrides:
        `broadcast` in class `javax.faces.component.UIComponentBase`
      Throws:
        `javax.faces.event.AbortProcessingException`
