public  void addActionListener(ActionListener listener)
Add a new ActionListener  to the set of listeners interested
in being notified when ActionEvent s occur.

 public MethodBinding getAction()Deprecated! This -  has been replaced by ActionSource2#getActionExpression .

If the implementing class also implements ActionSource2 , the implementation of this method must call
through to ActionSource2#getActionExpression  and examine
the result.  If the result came from a previous call to #setAction , extract the MethodBinding from it and
return it.  Otherwise, wrap the returned javax.el.MethodExpression  in a MethodBinding
implementation, and return it.

If the implementing class does not implement
ActionSource2, return the MethodBinding pointing at the application action to be invoked,
if this UIComponent  is activated by the user, during the
Apply Request Values or Invoke Application
phase of the request processing lifecycle, depending on the value
of the immediate property.

 public MethodBinding getActionListener()Deprecated! Use -  #getActionListeners  instead.

If #setActionListener  was not previously called
for this instance, this method must return null.  If
it was called, this method must return the exact
MethodBinding instance that was passed to #setActionListener .

 The method to be invoked, if this UIComponent  is
activated by the user, will be called during the Apply
Request Values or Invoke Application phase of the
request processing lifecycle, depending upon the value of the
immediate property.

 abstract public ActionListener[] getActionListeners()
Return the set of registered ActionListener s for this
ActionSource  instance.  If there are no registered listeners,
a zero-length array is returned.

 public boolean isImmediate()
Return a flag indicating that the default ActionListener 
provided by the JavaServer Faces implementation should be executed
immediately (that is, during Apply Request Values phase
of the request processing lifecycle), rather than waiting until the
Invoke Application phase.  The default value for this
property must be false.

 public  void removeActionListener(ActionListener listener)
Remove an existing ActionListener  (if any) from the set of
listeners interested in being notified when ActionEvent s
occur.

 public  void setAction(MethodBinding action)Deprecated! This -  has been replaced by ActionSource2#setActionExpression(javax.el.MethodExpression) .

If the implementing class also implements ActionSource2 , the implementation of this method must wrap the
argument action in a class that implements javax.el.MethodExpression  and call through to ActionSource2#setActionExpression , passing the wrapped
action.

If the implementing class does not implement
ActionSource2, set the MethodBinding 
pointing at the appication action to be invoked, if this UIComponent  is activated by the user, during the Apply
Request Values or Invoke Application phase of the
request processing lifecycle, depending on the value of the
immediate property.

Any method referenced by such an expression must be public, with
a return type of String, and accept no parameters.

 public  void setActionListener(MethodBinding actionListener)Deprecated! This -  has been replaced by #addActionListener(javax.faces.event.ActionListener) .

Wrap the argument actionListener in an
implementation of ActionListener 
and store it in the internal data structure that backs the #getActionListeners  method, taking care to over-write any
instance that was stored by a previous call to
setActionListener.

Any method referenced by such an expression must be public, with
a return type of void, and accept a single parameter of
type ActionEvent.

 public  void setImmediate(boolean immediate)
Set the "immediate execution" flag for this UIComponent .
