/**
 * 

This interface is implemented by classes * that need to save state that is expected to be available only within the scope * of the current request.

* *
* *

An implementor must implement both {@link * #saveTransientState} and {@link #restoreTransientState} methods in this class, since * these two methods have a tightly coupled contract between themselves. * In other words, if there is an inheritance hierarchy, it is not * permissible to have the {@link #saveTransientState} and {@link #restoreTransientState} * methods reside at different levels of the hierarchy.

* *

An example of transient state is the "submitted" property on forms.

* *
* * @since 2.1 */ public interface TransientStateHolder { /** *

Return the object containing related "transient states". * that could be used later to restore the "transient state".

* * @param context * @return object containing transient values * @since 2.1 */ public java.lang.Object saveTransientState(javax.faces.context.FacesContext context); /** *

Restore the "transient state" using the object passed as * state.

* *

If the state * argument is null clear any previous transient * state if any and return.
