javax.faces.component: public interface: PartialStateHolder

javax.faces.component
public interface: PartialStateHolder [javadoc | source]

All Implemented Interfaces:
StateHolder

Components that want to leverage the partial state saving feature must implement this interface instead of implementing StateHolder , from which this interface inherits.

since: 2.0 -

Method from javax.faces.component.PartialStateHolder Summary:
clearInitialState, initialStateMarked, markInitialState

Method from javax.faces.component.PartialStateHolder Detail:
public void clearInitialState() Reset the PartialStateHolder to a non-delta tracking state.
public boolean initialStateMarked() Return `true` if delta state changes are being tracked, otherwise `false`
public void markInitialState() The runtime must ensure that the #markInitialState method is called on each instance of this interface in the view at the appropriate time to indicate the component is in its initial state. The implementor of the interface must ensure that #initialStateMarked returns `true` from the time `markInitialState()` is called until #clearInitialState is called, after which time `initialStateMarked()` must return `false`. Also, during the time that the instance returns `true` from `initialStateMarked()`, the implementation must return only the state that has changed in its implementation of StateHolder#saveState .

 public  void markInitialState()The runtime must ensure that the
#markInitialState  method is called on each instance of
this interface in the view at the appropriate time to indicate
the component is in its initial state.  The implementor of the
interface must ensure that #initialStateMarked  returns
true from the time markInitialState()
is called until #clearInitialState  is called, after which
time initialStateMarked() must return
false.  Also, during the time that the instance
returns true from initialStateMarked(),
the implementation must return only the state that has changed in
its implementation of StateHolder#saveState .
