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.
