Class LocalObject

Implemented Interfaces:
Object
Known Direct Subclasses:
AbstractAny, CdrEncapsCodecImpl, gnuAdapterActivator, gnuClientRequestInfo, gnuCodecFactory, gnuDynAnyFactory, gnuIorInfo, gnuPOA, gnuPOAManager, gnuRuntime, gnuServerRequestInfo, Registrator
public class LocalObject
extends Object
implements Object
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.
Since:
1.4

Method Details

_create_request

public Request _create_request(Context context,
                               String operation,
                               NVList parameters,
                               NamedValue returns)
This method is not appropriate for the local objects and just throws an exception.
Specified by:
_create_request in interface Object

_create_request

public Request _create_request(Context context,
                               String operation,
                               NVList parameters,
                               NamedValue returns,
                               ExceptionList exceptions,
                               ContextList ctx_list)
This method is not appropriate for the local objects and just throws an exception.
Specified by:
_create_request in interface Object

_duplicate

public Object _duplicate()
This method is not appropriate for the local objects and just throws an exception.
Specified by:
_duplicate in interface Object

_get_domain_managers

public DomainManager[] _get_domain_managers()
This method is not appropriate for the local objects and just throws an exception.
Specified by:
_get_domain_managers in interface Object

_get_interface

public Object _get_interface()
This method is not appropriate for the local objects and just throws an exception.

_get_interface_def

public Object _get_interface_def()
This method is not appropriate for the local objects and just throws an exception.
Specified by:
_get_interface_def in interface Object

_get_policy

public Policy _get_policy(int a_policy_type)
            throws BAD_PARAM
This method is not appropriate for the local objects and just throws an exception.
Specified by:
_get_policy in interface Object

_hash

public int _hash(int maximum)
Specified by:
_hash in interface Object

_invoke

public InputStream _invoke(OutputStream output)
            throws ApplicationException,
                   RemarshalException
Invokes the operation. This method takes the OutputStream that was previously returned by a _request(String) and returns an InputStream which contains the reply. Up till jdk 1.5 inclusive this method is marked as unimplemented.
Throws:
NO_IMPLEMENT - always.

_is_a

public boolean _is_a(String repositoryIdentifer)
This method is not appropriate for the local objects and just throws an exception.
Specified by:
_is_a in interface Object

_is_equivalent

public boolean _is_equivalent(Object other)
Determines if the object is equal to another object, so far as it is possible to determine easily.
Specified by:
_is_equivalent in interface Object
Parameters:
other - the other object.
Returns:
true if the pased object is not null and java.lang.Object.equals(other) returns true. False otherwise.

_is_local

public boolean _is_local()
While it may look that this should return true, the jdk 1.5 API states that it must throw NO_IMPLEMENT instead. The rmi stubs do not call this method to check if the object is local; they call Util.isLocal(Stub) instead (passing this as parameter).
Returns:
never.
Throws:
NO_IMPLEMENT - always.

_non_existent

public boolean _non_existent()
Always returs false.
Specified by:
_non_existent in interface Object
Returns:
false, always.

_orb

public ORB _orb()
This method is not appropriate for the local objects and just throws an exception.

_release

public void _release()
This method is not appropriate for the local objects and just throws an exception.
Specified by:
_release in interface Object

_releaseReply

public void _releaseReply(InputStream input)
This method is not appropriate for the local objects and just throws an exception.

_request

public Request _request(String operation)
This method is not appropriate for the local objects and just throws an exception.
Specified by:
_request in interface Object

_request

public OutputStream _request(String operation,
                             boolean responseExpected)
This method is not appropriate for the local objects and just throws an exception.

_servant_postinvoke

public void _servant_postinvoke(ServantObject servant)
This method is called from rmic generated stubs if the Util.isLocal(Stub), called passing this as parameter, returns true, and the LocalObject 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.
Parameters:
servant - the object that has served as the invocation target for the current operation.

_set_policy_override

public Object _set_policy_override(Policy[] policies,
                                   SetOverrideType how)
This method is not appropriate for the local objects and just throws an exception.
Specified by:
