public interface TransientStateHolder

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 saveTransientState(jakarta.faces.context.FacesContext) and restoreTransientState(jakarta.faces.context.FacesContext, java.lang.Object) 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 saveTransientState(jakarta.faces.context.FacesContext) and restoreTransientState(jakarta.faces.context.FacesContext, java.lang.Object) methods reside at different levels of the hierarchy.

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