public Interface MutableActionParameters

Action parameters are additional portlet parameters added to the portlet URL or provided by the client that extend the state information provided by the render parameters. The client can supply additional action parameters when a form is submitted, for example.

The MutableActionParameters interface provides methods for modifying the action parameters attached to a portlet action URL.

If the MutableActionParameters object was retrieved from a URL, changes made will be applied to the URL. The modified parameters will be available during requests triggered by the URL.

RenderState provides a description of the render state. PortletParameters provides a description of the parameter concept.
