public interface State
extends java.io.Serializable

As it is said. Its a state. A state object is created by a StatefullComponent and is used to save and restore the state of that component. The state object must be immutable - and the restore methods must make sure that the state object's contents are not modified in any way.

Method Detail

restore

StatefullComponent restore(LayoutProcess layoutProcess)
                    throws StateException

Creates a restored instance of the saved component. By using this factory-like approach, we gain independence from having to know the actual implementation. This makes things a lot easier.

layoutProcess - the layout process that controls it all

Returns:

the saved state

StateException
