StateHolder
Gets the state of the instance as a
Serializable
Object.
If the class that implements this interface has references to
instances that implement StateHolder (such as a
UIComponent
with event handlers, validators, etc.)
this method must call the StateHolder.saveState(javax.faces.context.FacesContext)
method on all those
instances as well. This method must not save the state
of children and facets. That is done via the StateManager
This method must not alter the state of the implementing object. In other words, after executing this code:
Object state = component.saveState(facesContext);
component
should be the same as before executing
it.
The return from this method must be Serializable

public void restoreState(FacesContext context, java.lang.Object state)
StateHolder
Perform any processing required to restore the state from the entries in the state Object.
If the class that implements this interface has references to
instances that also implement StateHolder (such as a
UIComponent
with event handlers, validators, etc.)
this method must call the StateHolder.restoreState(javax.faces.context.FacesContext, java.lang.Object)
method on all those
instances as well.
If the state
argument is null
, take no action and return.
