31 * <P>Used as a base class for implementation of a local IDL interface in the
32 * Java language mapping. It is a class which implements all the operations
33 * in the <tt>org.omg.CORBA.Object</tt> interface.
34 * <P>Local interfaces are implemented by using CORBA::LocalObject
35 * to provide implementations of <code>Object</code> pseudo
36 * operations and any other ORB-specific support mechanisms that are
37 * appropriate for such objects. Object implementation techniques are
38 * inherently language-mapping specific. Therefore, the
39 * <code>LocalObject</code> type is not defined in IDL, but is specified
40 * in each language mapping.
41 * <P>Methods that do not apply to local objects throw
42 * an <code>org.omg.CORBA.NO_IMPLEMENT</code> exception with the message,
43 * "This is a locally contrained object." Attempting to use a
44 * <TT>LocalObject</TT> to create a DII request results in NO_IMPLEMENT
45 * system exception. Attempting to marshal or stringify a
46 * <TT>LocalObject</TT> results in a MARSHAL system exception. Narrowing
47 * and widening references to <TT>LocalObjects</TT> must work as for regular
48 * object references.
49 * <P><code>LocalObject</code> is to be used as the base class of locally
50 * constrained objects, such as those in the PortableServer module.
51 * The specification here is based on the CORBA Components
52 * Volume I - orbos/99-07-01<P>
