All Superinterfaces:

MimeResponse, PortletResponse

All Known Implementing Classes:

RenderResponseWrapper

public interface RenderResponse
extends MimeResponse

The RenderResponse defines an object to assist a portlet in sending a response to the portal. It extends the MimeResponse interface to provide specific render response functionality to portlets.
The portlet container creates a RenderResponse object and passes it as argument to the portlet's render method.

Method Detail

setTitle

@Deprecated
void setTitle(String title)

Deprecated.

This method sets the title of the portlet.

The value can be a text String

Parameters:

title - portlet title as text String or resource URI

setNextPossiblePortletModes

void setNextPossiblePortletModes(Collection<? extends PortletMode> portletModes)

This method allows the portlet to tell the portal the next possible portlet modes that the make sense from the portlet point of view.

If set, the portal should honor these enumeration of portlet modes and only provide the end user with choices to the provided portlet modes or a subset of these modes based on access control considerations.

If the portlet does not set any next possible portlet modes the default is that all portlet modes that the portlet has defined supporting in the portlet deployment descriptor are meaningful new portlet modes.

Parameters:

portletModes - Enumeration of objects of type PortletMode or any subtype of PortletMode with the next possible portlet modes that the make sense from the portlet point of view, must not be null or an empty enumeration.

Since:

2.0

setContentType

void setContentType(String type)

Sets the MIME type for the render response. The portlet should set the content type before calling MimeResponse.getWriter() or MimeResponse.getPortletOutputStream().

Calling setContentType after getWriter or getOutputStream does not change the content type.

The portlet container will ignore any character encoding specified as part of the content type for render calls.

Specified by:

setContentType in interface MimeResponse

Parameters:

type - the content MIME type

Throws:

IllegalArgumentException - if the given type is not in the list returned by PortletRequest.getResponseContentTypes
