public void
clearInitialState()

Implements javax.faces.component.PartialStateHolder.clearInitialState.

Reset the PartialStateHolder to a non-delta tracking state.

public boolean
initialStateMarked()

Implements javax.faces.component.PartialStateHolder.initialStateMarked.

Return true if delta state changes are being tracked, otherwise false

public boolean

If true, the Object implementing this interface must not participate in state saving or restoring.

markInitialState()

Implements javax.faces.component.PartialStateHolder.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.

public void markInitialState()

Implements javax.faces.component.PartialStateHolder.markInitialState.

Doc from javax.faces.component.PartialStateHolder.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 restoreState(FacesContext context, Object state)

Implements javax.faces.component.StateHolder.restoreState.

Doc from javax.faces.component.StateHolder.restoreState.

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 restoreState method on all those instances as well.

If the state argument is null, take no action and return.

Parameters
context:FacesContext

the Faces context.

state:Object

the state.

public Object saveState(FacesContext context)

Implements javax.faces.component.StateHolder.saveState.

Doc from javax.faces.component.StateHolder.saveState.

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 saveState method on all those instances as well. This method must not save the state of children and facets. That is done via the javax.faces.application.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

Parameters
context:FacesContext

the Faces context.

Returns:Object

the saved state.

public void setTransient(boolean newTransientValue)

Implements javax.faces.component.StateHolder.setTransient.

Doc from javax.faces.component.StateHolder.setTransient.

Denotes whether or not the Object implementing this interface must or must not participate in state saving or restoring.

Parameters
newTransientValue:boolean

boolean pass true if this Object will not participate in state saving or restoring, otherwise pass false.
