Interface TransientStateHelper
- All Superinterfaces:
- 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.
