Method Detail

setDelegate

public void setDelegate(Delegate delegate)

Description copied from interface: DynamicStub

Similar to ObjectImpl._set_delegate

Specified by:

setDelegate in interface DynamicStub

getDelegate

public Delegate getDelegate()

Description copied from interface: DynamicStub

Similar to ObjectImpl._get_delegate

Specified by:

getDelegate in interface DynamicStub

getORB

public ORB getORB()

Description copied from interface: DynamicStub

Similar to ObjectImpl._orb()

Specified by:

getORB in interface DynamicStub

getTypeIds

public String[] getTypeIds()

Description copied from interface: DynamicStub

Similar to ObjectImpl._ids

Specified by:

getTypeIds in interface DynamicStub

connect

public void connect(ORB orb)
             throws RemoteException

Description copied from interface: DynamicStub

Connect this dynamic stub to an ORB. Just as in standard RMI-IIOP, this is required after a dynamic stub is deserialized from an ObjectInputStream. It is not needed when unmarshalling from a org.omg.CORBA.portable.InputStream.

Specified by:

connect in interface DynamicStub

Throws:

RemoteException

isLocal

public boolean isLocal()

Specified by:

isLocal in interface DynamicStub

request

public OutputStream request(String operation,
                            boolean responseExpected)

Specified by:

request in interface DynamicStub

_is_a

public boolean _is_a(String repositoryIdentifier)

Description copied from interface: Object

Checks whether this object is an instance of a class that implements the given interface.

Specified by:

_is_a in interface Object

Parameters:

repositoryIdentifier - the interface to check against

Returns:

true if this object reference is an instance of a class that implements the interface; false otherwise

_is_equivalent

public boolean _is_equivalent(Object other)

Description copied from interface: Object

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.

Specified by:

_is_equivalent in interface Object

Parameters:

other - the other object reference with which to check for equivalence

Returns:

true if this object reference is known to be equivalent to the given object reference. Note that false indicates only that the two object references are distinct, not necessarily that they reference distinct objects.

_non_existent

public boolean _non_existent()

Description copied from interface: Object

Determines whether the server object for this object reference has been destroyed.

Specified by:

_non_existent in interface Object

Returns:

true if the ORB knows authoritatively that the server object does not exist; false otherwise

_hash

public int _hash(int maximum)

Description copied from interface: Object

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.

Specified by:

_hash in interface Object

Parameters:

maximum - the upper bound on the hash value returned by the ORB

Returns:

the ORB-internal hash identifier for this object reference

_duplicate

public Object _duplicate()

Description copied from interface: Object

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.

Specified by:

_duplicate in interface Object

Returns:

a duplicate of this object reference or this object reference itself

_release

public void _release()

Description copied from interface: Object

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.

Specified by:

_release in interface Object

_get_interface_def

public Object _get_interface_def()

Description copied from interface: Object

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.

Specified by:

_get_interface_def in interface Object

Returns:

the InterfaceDef object in the Interface Repository which provides type information about the object referred to by this object reference

_request

public Request _request(String operation)

Description copied from interface: Object

Creates a Request instance for use in the Dynamic Invocation Interface.

Specified by:

_request in interface Object

Parameters:

operation - the name of the method to be invoked using the Request instance

Returns:

the newly-created Request instance

_create_request

Returns:

A Policy object of the type specified by the policy_type parameter

_get_domain_managers

public DomainManager[] _get_domain_managers()

Specified by:

_get_domain_managers in interface Object

Returns:

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.

_set_policy_override

public Object _set_policy_override(Policy[] policies,
                                   SetOverrideType set_add)

Description copied from interface: Object

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.

Specified by:

_set_policy_override in interface Object

Parameters:

policies - an array of Policy objects containing the policies to be added or to be used as replacements

set_add - either SetOverrideType.SET_OVERRIDE, indicating that the given policies will replace any existing ones, or SetOverrideType.ADD_OVERRIDE, indicating that the given policies should be added to any existing ones

Returns:

a new Object with the given policies replacing or added to those in this Object
