Class MethodBindingValueChangeListener

java.lang.Object

javax.faces.component.MethodBindingAdapterBase

javax.faces.component.MethodBindingValueChangeListener

All Implemented Interfaces:

java.util.EventListener, StateHolder, FacesListener, ValueChangeListener

class MethodBindingValueChangeListener
extends MethodBindingAdapterBase
implements ValueChangeListener, StateHolder

MethodBindingValueChangeListener is an ValueChangeListenerListener that wraps a MethodBinding. When it receives a ValueChangeEvent, it executes a method on an object identified by the MethodBinding.

public MethodBindingValueChangeListener(MethodBinding methodBinding)

Construct a ValueChangeListener that contains a MethodBinding.

Method Detail

getWrapped

public MethodBinding getWrapped()

processValueChange

public void processValueChange(ValueChangeEvent actionEvent)
                        throws AbortProcessingException

Description copied from interface: ValueChangeListener

Invoked when the value change described by the specified ValueChangeEvent occurs.

Specified by:

processValueChange in interface ValueChangeListener

Parameters:

actionEvent - The ValueChangeEvent that has occurred

Throws:

java.lang.NullPointerException

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

saveState

public java.lang.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

restoreState

public void restoreState(FacesContext context,
                         java.lang.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

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

setTransient

public void setTransient(boolean newTransientValue)

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:

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

loadClass

private static java.lang.Class loadClass(java.lang.String name,
                                         java.lang.Object fallbackClass)
                                  throws java.lang.ClassNotFoundException

Throws:

java.lang.ClassNotFoundException
