Interface IValuePersister

All Superinterfaces:

IClusterable, java.io.Serializable

All Known Implementing Classes:

CookieValuePersister

public interface IValuePersister
extends IClusterable

Wicket users and developers should not need to care about where or how form values are saved. An implementer of IValuePersister persister is responsible for storing and retrieving FormComponent values. Different means of storing values for form components may be implemented. CookieValuePersister, for example, uses an HTTP cookie to persist the value of a form component. Other implementations may instead persist form values to server-side storage for security reasons.
