Interface TransientStateHelper
- 
- All Superinterfaces:
- TransientStateHolder
 
 public interface TransientStateHelper extends TransientStateHolder Define a Map-like contract that makes it easier for components to implementTransientStateHolder. EachUIComponentin the view will return an implementation of this interface from itsUIComponent.getTransientStateHelper()method.The values retrieved or saved through getTransient(java.lang.Object)orputTransient(java.lang.Object, java.lang.Object)will not be preserved between requests.- Since:
