Interface PortletResponse

All Known Subinterfaces:

ActionResponse, RenderResponse, WindowActionResponse

public interface PortletResponse

The PortletResponse defines the base interface to assist a portlet in creating and sending a response to the client. The portlet container uses two specialized versions of this interface when invoking a portlet, ActionResponse and RenderResponse. The portlet container creates these objects and passes them as arguments to the portlet's processAction and render methods.

Method Detail

addProperty

void addProperty(String key,
                 String value)

Adds a String property to an existing key to be returned to the portal.

This method allows response properties to have multiple values.

Properties can be used by portlets to provide vendor specific information to the portal.

Parameters

key - the key of the property to be returned to the portal

value - the value of the property to be returned to the portal

Throws

IllegalArgumentException - if key is null.

setProperty

void setProperty(String key,
                 String value)

Sets a String property to be returned to the portal.

Properties can be used by portlets to provide vendor specific information to the portal.

This method resets all properties previously added with the same key.

Parameters

key - the key of the property to be returned to the portal

value - the value of the property to be returned to the portal

Throws

IllegalArgumentException - if key is null.

encodeURL

String encodeURL(String path)

Returns the encoded URL of the resource, like servlets, JSPs, images and other static files, at the given path.

Some portal/portlet-container implementation may require those URLs to contain implementation specific data encoded in it. Because of that, portlets should use this method to create such URLs.

The encodeURL method may include the session ID and other portal/portlet-container specific information into the URL. If encoding is not needed, it returns the URL unchanged.

Parameters

path - the URI path to the resource. This must be either an absolute URL (e.g. http://my.co/myportal/mywebap/myfolder/myresource.gif) or a full path URI (e.g. /myportal/mywebap/myfolder/myresource.gif).

Returns

the encoded resource URL as string

Throws

IllegalArgumentException - if path doesn't have a leading slash or is not an absolute URL
