public interface TransientStateHelper extends TransientStateHolder
Define a Map
-like contract
that makes it easier for components to implement TransientStateHolder
. Each UIComponent
in the view will
return an implementation of this interface from its UIComponent.getTransientStateHelper()
method.
The values retrieved or saved through getTransient(java.lang.Object)
or putTransient(java.lang.Object, java.lang.Object)
will not be
preserved between requests.
