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