Examples of org.apache.lucene.gdata.data.ServerBaseEntry

org.apache.lucene.gdata.data.ServerBaseEntry
The GData-Server uses the GDATA-Client API for an interal representation of entries. These entities have dynamic elements like Links being generated using the requested URL.
Some components of the server also need additional infomation like the service type {@link org.apache.lucene.gdata.server.registry.ProvidedService} of the entryand the feedid a entry belongs to. All these information are encapsulated in the ServerBaseEntry decorating a concrete sub class of BaseEntry. The actual {@link com.google.gdata.data.BaseEntry} will be passed to the ServerBaseEntryat creation time via the constructor. To use the ServerBaseFeed for generation a provided format like RSS/ATOM the corresponding {@link com.google.gdata.data.ExtensionProfile} hasto be provided to the generation method.
For a general overview of the generic BaseFeed class see the gdata-client API documentation
