Class ComponentReferencingComponentChangeFilter<T extends javax.faces.component.UIComponent>

java.lang.Object
org.apache.myfaces.trinidad.change.ComponentChangeFilter
org.apache.myfaces.trinidad.change.ComponentReferencingComponentChangeFilter<T>

Type Parameters:

T - The type of UIComponent that this filter can keep references to

All Implemented Interfaces:

Serializable

public abstract class ComponentReferencingComponentChangeFilter<T extends javax.faces.component.UIComponent>

extends ComponentChangeFilter

ComponentChangeFilter implementation that keeps reference to a Component. It is not appropriate for listeners to hold references to UIComponent instances beyond the request scope. This filter implementation converts the supplied component into a ComponentReference giving two advantages 1. Listeners can hold on to such filters beyond request scope 2. Takes care of serialization of the referenced component One of the uses of this class is to keep a reference to a root of a component subtree, and then filter ComponentChanges based on whether the target component of the ComponentChange belongs to the subtree.
