Method Detail

processAction

public void processAction(ActionEvent e)
                   throws AbortProcessingException

Description copied from interface: ActionListener

Invoked when the action described by the specified ActionEvent occurs.

Specified by:

processAction in interface ActionListener

Parameters:

e - The ActionEvent that has occurred

Throws:

AbortProcessingException - Signal the Jakarta Server Faces implementation that no further processing on the current event should be performed

setTransient

public void setTransient(boolean trans)

Description copied from interface: StateHolder

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

Specified by:

setTransient in interface StateHolder

Parameters:

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

isTransient

public boolean isTransient()

Description copied from interface: StateHolder

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

Specified by:

isTransient in interface StateHolder

Returns:

true if transient, false otherwise.

saveState

public Object saveState(FacesContext context)

Description copied from interface: 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

Specified by:

saveState in interface StateHolder

Parameters:

context - the Faces context.

Returns:

the saved state.

restoreState

public void restoreState(FacesContext context,
                         Object state)

Description copied from interface: 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.

Specified by:

restoreState in interface StateHolder

Parameters:

context - the Faces context.

state - the state.
