Programming tips: wrapper objects

To enable the easy usage of portlet filters, HCL Portal provides a predefined set of wrapper objects. You can use these wrapper objects to modify the standard behavior of the wrapped components.

Wrappers are defined for the following objects:

Object	Predefined wrapper
PortletRequest	PortletRequestWrapper
PortletResponse	PortletResponseWrapper
Client	ClientWrapper

A transcoding filter for markups, for example, from HTML to WML needs to use all of these wrappers to emulate the HTML environment that an HTML portlet assumes.
