can you list methods in the portlet interface?

 The Portlet  interface is used by the portlet container to   invoke the portlets. Every portlet has to implement this interface,  either by directly implementing it, or by using an existing class
  implementing the Portlet interface.


the portlet interface has four methods

1. init(PortletConfig pc)

2. render(RenderRequest rreq, RenderResponse res)

3.processAction(ActionRequest areq, ActionResponse aresp)

4.destroy()
