GDataEntityBuilder

public class GDataEntityBuilder extends Object
{@link com.google.gdata.data.BaseFeed}, {@link com.google.gdata.data.BaseEntry} instances have to be build from a {@link java.io.Reader} instance as they come in from a client request or out of a storage.

To provide a generic builder class the {@link GDataEntityBuilder} requests the type of the feed / entry and the corresponding {@link com.google.gdata.data.ExtensionProfile} form the global {@link org.apache.lucene.gdata.server.registry.GDataServerRegistry} and builds the instances from the provided reader.

This build will not returne the abstract base classes.
