| org.omg.CORBA.Object
All known Subclasses: org.omg.CORBA.LocalObject, org.omg.CORBA.portable.ObjectImpl,
| Object | | public interface Object (Code) | | The definition for a CORBA object reference.
A CORBA object reference is a handle for a particular
CORBA object implemented by a server. A CORBA object reference
identifies the same CORBA object each time the reference is used to invoke
a method on the object.
A CORBA object may have multiple, distinct object references.
The org.omg.CORBA.Object interface is the root of
the inheritance hierarchy for all CORBA object references in the Java
programming language, analogous to java.rmi.Remote
for RMI remote objects.
A CORBA object may be either local or remote.
If it is a local object (that is, running in the same
VM as the client), invocations may be directly serviced by
the object instance, and the object reference could point to the actual
instance of the object implementation class.
If a CORBA object is a remote object (that is, running in a different
VM from the client), the object reference points to a stub (proxy) which uses the
ORB machinery to make a remote invocation on the server where the object
implementation resides.
Default implementations of the methods in the interface
org.omg.CORBA.Object
are provided in the class org.omg.CORBA.portable.ObjectImpl,
which is the base class for stubs and object implementations.

| Method Summary | |
| Request | _create_request(Context ctx, String operation, NVList arg_list, NamedValue result)
Creates a Request instance initialized with the
given context, method name, list of arguments, and container
for the method's return value. | | Request | _create_request(Context ctx, String operation, NVList arg_list, NamedValue result, ExceptionList exclist, ContextList ctxlist)
Creates a Request instance initialized with the
given context, method name, list of arguments, container
for the method's return value, list of possible exceptions,

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. | | boolean | _is_a(String repositoryIdentifier)

so far as the ORB can easily determine. | | boolean | _non_existent()
Determines whether the server object for this object reference has been
destroyed. | | void | _release()
Signals that the caller is done using this object reference, so
internal ORB resources associated with this object reference can be
released. | | Request | _request(String operation)
Creates a Request instance for use in the
Dynamic Invocation Interface. | | org.omg.CORBA.Object | _set_policy_override(Policy[] policies, SetOverrideType set_add)
Returns a new Object with the given policies
either replacing any existing policies in this
Object or with the given policies added
to the existing ones, depending on the value of the
given SetOverrideType object. |
| _create_request | | Request _create_request(Context ctx, String operation, NVList arg_list, NamedValue result)(Code) | | Creates a Request instance initialized with the
given context, method name, list of arguments, and container
for the method's return value.
Parameters:
ctx - a Context object containinga list of properties
Parameters:
operation - the name of the method to be invoked
Parameters:
arg_list - an NVList containing the actual argumentsto the method being invoked
Parameters:
result - a NamedValue object to serve as acontainer for the method's return value the newly-created Request object

| _create_request | | Request _create_request(Context ctx, String operation, NVList arg_list, NamedValue result, ExceptionList exclist, ContextList ctxlist)(Code) | | Creates a Request instance initialized with the
given context, method name, list of arguments, container
for the method's return value, list of possible exceptions,
and list of context strings needing to be resolved.
Parameters:
ctx - a Context object containinga list of properties
Parameters:
operation - the name of the method to be invoked
Parameters:
arg_list - an NVList containing the actual argumentsto the method being invoked
Parameters:
result - a NamedValue object to serve as acontainer for the method's return value
Parameters:
exclist - an ExceptionList object containing alist of possible exceptions the method can throw
Parameters:
ctxlist - a ContextList object containing a list ofcontext strings that need to be resolved and sent with theRequest instance the newly-created Request object

| _duplicate | | org.omg.CORBA.Object _duplicate()(Code) | | 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.
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.
The method _duplicate may return this object reference itself.
a duplicate of this object reference or this object referenceitself |
| _get_domain_managers | | DomainManager[] _get_domain_managers()(Code) | | Retrieves the DomainManagers of this object.
This allows administration services (and applications) to retrieve the
domain managers, and hence the security and other policies applicable
to individual objects that are members of the domain.
the list of immediately enclosing domain managers of this object.At least one domain manager is always returned in the list since by default each object is associated with at least one domain manager at creation. |
| _get_interface_def | | org.omg.CORBA.Object _get_interface_def()(Code) | | Obtains an InterfaceDef for the object implementation
referenced by this object reference.
The InterfaceDef object
may be used to introspect on the methods, attributes, and other
type information for the object referred to by this object reference.
the InterfaceDef object in the Interface Repositorywhich provides type information about the object referred to bythis object reference |
| _get_policy | | Policy _get_policy(int policy_type)(Code) | | Returns the Policy object of the specified type
which applies to this object.
Parameters:
policy_type - the type of policy to be obtained A Policy object of the type specified by the policy_type parameter
exception:
org.omg.CORBA.BAD_PARAM - when the value of policy type is not valid either because the specified type is not supported by this ORB or because a policy object of that type is not associated with this Object |
| _hash | | int _hash(int maximum)(Code) | | 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.
Parameters:
maximum - the upper bound on the hash value returned by the ORB the ORB-internal hash identifier for this object reference |
| _is_a | | boolean _is_a(String repositoryIdentifier)(Code) | | Checks whether this object is an instance of a class that
implements the given interface.
Parameters:
repositoryIdentifier - the interface to check against true if this object reference is an instanceof a class that implements the interface;false otherwise |
| _is_equivalent | | boolean _is_equivalent(org.omg.CORBA.Object other)(Code) | | 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.
Parameters:
other - the other object reference with which to check for equivalence true if this object reference is known to beequivalent to the given object reference.Note that false indicates only that the twoobject references are distinct, not necessarily thatthey reference distinct objects. |
| _non_existent | | boolean _non_existent()(Code) | | Determines whether the server object for this object reference has been
destroyed.
true if the ORB knows authoritatively that theserver object does not exist; false otherwise |
| _release | | void _release()(Code) | | 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.
|
| _request | | Request _request(String operation)(Code) | | Creates a Request instance for use in the
Dynamic Invocation Interface.
Parameters:
operation - the name of the method to be invoked using theRequest instance the newly-created Request instance |
| _set_policy_override | | org.omg.CORBA.Object _set_policy_override(Policy[] policies, SetOverrideType set_add)(Code) | | Returns a new Object with the given policies
either replacing any existing policies in this
Object or with the given policies added
to the existing ones, depending on the value of the
given SetOverrideType object.
Parameters:
policies - an array of Policy objects containingthe policies to be added or to be used as replacements
Parameters:
set_add - either SetOverrideType.SET_OVERRIDE, indicatingthat the given policies will replace any existing ones, orSetOverrideType.ADD_OVERRIDE, indicating thatthe given policies should be added to any existing ones a new Object with the given policies replacingor added to those in this Object |
