Interface AttachedObjectTarget
- All Known Subinterfaces:
ActionSource2AttachedObjectTarget
,BehaviorHolderAttachedObjectTarget
,EditableValueHolderAttachedObjectTarget
,ValueHolderAttachedObjectTarget
Within the declaration of a
composite component, an AttachedObjectTarget
allows the composite component author to expose the
semantics of an inner component to the page author without
exposing the rendering or implementation details of the inner
component. See ViewDeclarationLanguage.getComponentMetadata(javax.faces.context.FacesContext, javax.faces.application.Resource)
for the context in
which implementations of this interface are used.
The implementation must ensure that this instance is thread safe and may be shared among different component trees.
Subinterfaces are provided for the common behavioral interfaces:
Behavior
, ValueHolder
, EditableValueHolder
and ActionSource2
. The default VDL implementation
must provide a corresponding Facelets tag handler for each of the
subinterfaces of this interface.

getTargets
Returns the
List<UIComponent>
that thisAttachedObjectTarget
exposes. Each attached object exposed by the composite component author may point at multipleUIComponent
instances within the composite component. This method is used by theViewDeclarationLanguage.retargetAttachedObjects(javax.faces.context.FacesContext, javax.faces.component.UIComponent, java.util.List<javax.faces.view.AttachedObjectHandler>)
method to take the appropriate action on the attached object. -
