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.
