| ExternalizableUtil | | public class ExternalizableUtil (Code) | | Utility methods to assist in working with the Externalizable interfaces. This class
is only used when running inside of a Cluser. When using the open source version
this class will use a dummy implementation. Anyway, this class is not used when
not using the Enterprise edition.
ExternalizableLite is very similar to the standard Externalizable interface, except that
it uses DataOutput/DataInput instead of the Object stream equivalents.
