java.lang.Objectorg.omg.CORBA.LocalObject
public class LocalObject
An object, formally implementing the CORBA Object, but actually
handling all invocations locally.
Various calls to the remote object specific methods throw the
NO_IMPLEMENT. The explaining message for this exception is
specified in java API as "This is a locally constrained object.".
It is not possible to get a stringified reference of the local object, or
invoke a method using DII (by name via Request class).
However narrowing and widening methods will work with local objects.

boolean |
_is_equivalent(Object other)
Determines if the object is equal to another object, so far as it is possible to determine easily. |

OutputStream |
_request(String operation,
boolean responseExpected)
This method is not appropriate for the local objects and just throws an exception. |
void |
_servant_postinvoke(ServantObject servant)
This method is called from rmic generated stubs if the
Util.isLocal(javax.rmi.CORBA.Stub), called passing this as parameter,
returns true, and the _servant_preinvoke(java.lang.String, java.lang.Class) return non-null object. |
ServantObject |
_servant_preinvoke(String operation,
Class expectedType)
This method is called from rmic generated stubs if the

public Request _create_request(Context context,
String operation,
NVList parameters,

_create_request in interface Objectcontext - a list of additional properties.operation - the name of method to be invoked.parameters - the method parameters.returns - the container for tge method returned value.
NO_IMPLEMENT, - always.

can throw.ctx_list - the list of the context strings that need to be
resolved and send as a context instance.
NO_IMPLEMENT, - always.public Object _duplicate()
_duplicate in interface Objectthis.
NO_IMPLEMENT, - always.public DomainManager[] _get_domain_managers()
_get_domain_managers in interface ObjectNO_IMPLEMENT, - always.public Object _get_interface_def()

NO_IMPLEMENT, - always.
public Policy _get_policy(int a_policy_type)
throws BAD_PARAM
_get_policy in interface Objecta_policy_type - a type of policy to be obtained.
NO_IMPLEMENT, - always.
BAD_PARAM - if the policy of the given type is not
associated with this object, or if it is not supported by this ORB.public int _hash(int maximum)
_hash in interface Objectmaximum - the maximal value to return.
public boolean _is_a(String repositoryIdentifer)
_is_a in interface ObjectrepositoryIdentifer - the repository id.
NO_IMPLEMENT, - always.public boolean _is_equivalent(Object other)
_is_equivalent in interface Objectother - the other object.
public boolean _non_existent()
_non_existent in interface Objectpublic void _release()

_request in interface Objectoperation - the name of the method to invoke.
NO_IMPLEMENT, - always.
public Object _set_policy_override(Policy[] policies,
SetOverrideType how)
_set_policy_override in interface Objectpolicies - the policy additions or replacements.how - either SetOverrideType.SET_OVERRIDE to override the
current policies of SetOverrideType.ADD_OVERRIDE to replace
them.
NO_IMPLEMENT, - always.
public ServantObject _servant_preinvoke(String operation,
Class expectedType)
rmic generated stubs if the
Util.isLocal(javax.rmi.CORBA.Stub), called passing this as parameter,
returns true. If the method returns null, the requested method is then
invoked on this. Else it is invoked on the returned object,
casting it into the interface that the local object implements. In this
case, the generated stub also later calls
_servant_postinvoke(ServantObject), passing that returned target
as parameter.
operation - the name of the method being invoked.expectedType - the interface that the returned servant
object must implement.
NO_IMPLEMENT - always. If used, the method must be overridden.public void _servant_postinvoke(ServantObject servant)
rmic generated stubs if the
Util.isLocal(javax.rmi.CORBA.Stub), called passing this as parameter,
returns true, and the _servant_preinvoke(java.lang.String, java.lang.Class) return non-null object.
The stub then invokes the requrested method on that returned object and
later calls _servant_postinvoke, passing that returned target as parameter.
servant - the object that has served as the invocation target for the
current operation.
public InputStream _invoke(OutputStream output)
throws ApplicationException,
RemarshalException
_request(String) and returns an InputStream which
contains the reply. Up till jdk 1.5 inclusive this method is marked as
unimplemented.
NO_IMPLEMENT - always.
