Examples of org.apache.jetspeed.om.page.ContentPage

org.apache.jetspeed.om.page.ContentPage
PageFragment is a volatile wrapper around a {@link org.apache.jetspeed.om.page.Page} metadataobject for use in rendering. As with the {@link org.apache.jetspeed.om.page.Fragment} object,Page objects are persistent, single-instance metadata objects that should not be used to hold per-request content. ContentPage solves this by providing a thin, wrapper interface that can be used for rendering requested content associated with the wrapped page relative to the currect user-request. @author weaver@apache.org
