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, setImmediateMethodExpression 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(jakarta.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.
