public interface ActionSource2 extends ActionSource
ActionSource2 extends ActionSource
and provides a JavaBeans property
analogous to the "action
" property on ActionSource
. The difference is
the type of this property is a MethodExpression
rather than a MethodBinding
.
This allows the ActionSource
concept to leverage the Jakarta Expression Language API.
Modifier and Type | Method and Description |

MethodExpression |
getActionExpression()
Return the
MethodExpression 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. |
void |
setActionExpression(MethodExpression action)
Set the
MethodExpression 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. |
addActionListener, getAction, getActionListener, getActionListeners, isImmediate, removeActionListener, setAction, setActionListener, setImmediate
MethodExpression getActionExpression()
Return the MethodExpression
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.
Note that it's possible that the returned MethodExpression
is just a wrapper
around a MethodBinding
instance whith was set by a call to
ActionSource.setAction(javax.faces.el.MethodBinding)
. This makes it possible for the default ActionListener
to continue to work properly with older components.
void setActionExpression(MethodExpression action)
Set the MethodExpression
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.
