 implements the given interface.<DD><DL>
<DT><B>Parameters:</B><DD><CODE>repositoryIdentifier</CODE> - the interface to check against<DT><B>Returns:</B><DD><code>true</code> if this object reference is an instance
         of a class that implements the interface;
         <code>false</code> otherwise</DL>
</DD>

<A NAME="_is_equivalent(org.omg.CORBA.Object)"><!-- --></A><H3>
_is_equivalent</H3>
<PRE>
public boolean <B>_is_equivalent</B>(<A HREF="../../../org/omg/CORBA/Object.html">Object</A>&nbsp;other)</PRE>
<DL>
<DD>Determines whether the two object references are equivalent,
 so far as the ORB can easily determine. Two object references are equivalent
 if they are identical. Two distinct object references which in fact refer to
 the same object are also equivalent. However, ORBs are not required
 to attempt determination of whether two distinct object references
 refer to the same object, since such determination could be impractically
 expensive.<DD><DL>
<DT><B>Parameters:</B><DD><CODE>other</CODE> - the other object reference with which to check for equivalence<DT><B>Returns:</B><DD><code>true</code> if this object reference is known to be
         equivalent to the given object reference.
         Note that <code>false</code> indicates only that the two
         object references are distinct, not necessarily that
         they reference distinct objects.</DL>
</DD>
</DL>
<HR>

<A NAME="_non_existent()"><!-- --></A><H3>
_non_existent</H3>
<PRE>
public boolean <B>_non_existent</B>()</PRE>
<DL>
<DD>Determines whether the server object for this object reference has been
 destroyed.<DD><DL>
<DT><B>Returns:</B><DD><code>true</code> if the ORB knows authoritatively that the
         server object does not exist; <code>false</code> otherwise</DL>
</DD>
</DL>
<HR>

<A NAME="_hash(int)"><!-- --></A><H3>
_hash</H3>
<PRE>
public int <B>_hash</B>(int&nbsp;maximum)</PRE>
<DL>
<DD>Returns an ORB-internal identifier for this object reference.
 This is a hash identifier, which does
 not change during the lifetime of the object reference, and so
 neither will any hash function of that identifier change. The value returned
 is not guaranteed to be unique; in other words, another object
 reference may have the same hash value.
 If two object references hash differently,
 then they are distinct object references; however, both may still refer
 to the same CORBA object.<DD><DL>
<DT><B>Parameters:</B><DD><CODE>maximum</CODE> - the upper bound on the hash value returned by the ORB<DT><B>Returns:</B><DD>the ORB-internal hash identifier for this object reference</DL>
</DD>
</DL>
<HR>

<A NAME="_duplicate()"><!-- --></A><H3>
_duplicate</H3>
<PRE>
public <A HREF="../../../org/omg/CORBA/Object.html">Object</A> <B>_duplicate</B>()</PRE>
<DL>
<DD>Returns a duplicate of this CORBA object reference.
 The server object implementation is not involved in creating
 the duplicate, and the implementation cannot distinguish whether
 the original object reference or a duplicate was used to make a request.
 <P>
 Note that this method is not very useful in the Java platform,
 since memory management is handled by the VM.
 It is included for compliance with the CORBA APIs.
 <P>
 The method <code>_duplicate</code> may return this object reference itself.<DD><DL>
<DT><B>Returns:</B><DD>a duplicate of this object reference or this object reference
         itself</DL>
</DD>
</DL>
<HR>

<A NAME="_release()"><!-- --></A><H3>
_release</H3>
<PRE>
public void <B>_release</B>()</PRE>
<DL>
<DD>Signals that the caller is done using this object reference, so
 internal ORB resources associated with this object reference can be
 released. Note that the object implementation is not involved in
 this operation, and other references to the same object are not affected.</DL>
<HR>

<A NAME="_get_interface_def()"><!-- --></A><H3>
_get_interface_def</H3>
<PRE>
public <A HREF="../../../org/omg/CORBA/Object.html">Object</A> <B>_get_interface_def</B>()</PRE>
<DL>
<DD>Obtains an <code>InterfaceDef</code> for the object implementation
 referenced by this object reference.
 The <code>InterfaceDef</code> object
 may be used to introspect on the methods, attributes, and other
 type information for the object referred to by this object reference.<DD><DL>
<DT><B>Returns:</B><DD>the <code>InterfaceDef</code> object in the Interface Repository
         which provides type information about the object referred to by
         this object reference</DL>
