Interface ICallback

All Superinterfaces:

java.io.Serializable

All Known Implementing Classes:

DirectCallback, ExternalCallback, PageCallback

public interface ICallback
extends java.io.Serializable

Defines a callback, an object which is used to invoke or reinvoke a method on an object or component in a later request cycle. This is used to allow certain operations (say, submitting an order) to defer to other processes (say, logging in and/or registerring).

Callbacks must be Serializable, to ensure that they can be stored between request cycles.
