public interface ActionSource
ActionSource is an interface that may be implemented
by any concrete UIComponent that wishes to be a source of
ActionEvents, including the ability to invoke application
actions via the default ActionListener mechanism.
| Modifier and Type | Method and Description |
|---|---|
void |
addActionListener(ActionListener listener)
Add a new
ActionListener to the set of listeners interested
in being notified when ActionEvents occur. |
MethodBinding |
getAction()
Deprecated.
This has been replaced by
ActionSource2.getActionExpression(). |
MethodBinding |
getActionListener()
Deprecated.
Use
getActionListeners() instead. |
ActionListener[] |
getActionListeners()
Return the set of registered
ActionListeners for this
ActionSource instance. |
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. |
void |
removeActionListener(ActionListener listener)
Remove an existing
ActionListener (if any) from the set of
listeners interested in being notified when ActionEvents
occur. |
void |
setAction(MethodBinding action)
Deprecated.
This has been replaced by
ActionSource2.setActionExpression(javax.el.MethodExpression). |
void |
setActionListener(MethodBinding actionListener)
Deprecated.
This has been replaced by
addActionListener(javax.faces.event.ActionListener). |
void |
setImmediate(boolean immediate)
Set the "immediate execution" flag for this
UIComponent. |
MethodBinding getAction()
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(javax.faces.el.MethodBinding), extract the MethodBinding from it and
return it. Otherwise, wrap the returned MethodExpression in a MethodBinding
implementation, and return it.
If the implementing class does not implement
ActionSource2, return the MethodBindingpointing 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.
void setAction(MethodBinding action)
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 MethodExpression and call through to ActionSource2.setActionExpression(javax.el.MethodExpression), 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.
action - The new MethodBinding expressionMethodBinding getActionListener()
getActionListeners() instead.If setActionListener(javax.faces.el.MethodBinding) 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(javax.faces.el.MethodBinding).
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.
void setActionListener(MethodBinding actionListener)
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.
actionListener - The new method binding expressionboolean 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.
true if immediate, false otherwise.void setImmediate(boolean immediate)
Set the "immediate execution" flag for this UIComponent.
immediate - The new immediate execution flagvoid addActionListener(ActionListener listener)
Add a new ActionListener to the set of listeners interested
in being notified when ActionEvents occur.
listener - The ActionListener to be addedNullPointerException - if listener
is nullActionListener[] getActionListeners()
Return the set of registered ActionListeners for this
ActionSource instance. If there are no registered listeners,
a zero-length array is returned.
void removeActionListener(ActionListener listener)
Remove an existing ActionListener (if any) from the set of
listeners interested in being notified when ActionEvents
occur.
