Constructor Summary

PortableRemoteObjectDelegateImpl()

Method Summary

void	connect(java.rmi.Remote target, java.rmi.Remote source) This method makes the remote object target ready for remote communication using the same communications runtime as source.
void	exportObject(java.rmi.Remote obj) A call to this method with no objects exported creates a non-daemon thread wich keeps the java virtual machine alive until all exported objects have been unexported by calling unexportObject.
java.lang.Object	narrow(java.lang.Object obj, java.lang.Class newClass) This method takes an object reference or an object of an RMI/IDL abstract interface type and attemps to narrow it to conform to the given newClass RMI/IDL type.
java.rmi.Remote	toStub(java.rmi.Remote obj) This method takes a server implementation object and returns a stubobject that can be used to access that server object.
java.lang.Object	uncheckedNarrow(java.lang.Object obj, java.lang.Class newClass) This method takes an object reference or an object of an RMI/IDL abstract interface type and attemps to narrow it to conform to the given newClass RMI/IDL type.
void	unexportObject(java.rmi.Remote obj) This method is used to deregister a currently exported server object from the ORB runtimes, allowing the object to become available for garbage collection.

Method Detail

exportObject

public void exportObject(java.rmi.Remote obj)
                  throws java.rmi.RemoteException

A call to this method with no objects exported creates a non-daemon thread wich keeps the java virtual machine alive until all exported objects have been unexported by calling unexportObject.

Specified by:

exportObject in interface javax.rmi.CORBA.PortableRemoteObjectDelegate

toStub

public java.rmi.Remote toStub(java.rmi.Remote obj)
                       throws java.rmi.NoSuchObjectException

This method takes a server implementation object and returns a stubobject that can be used to access that server object. The argument object must currently be exported, either because it is a subclass f PortableRemoteObject or be virtue of a previous call to PortableRemoteObject.exportObject.

Specified by:

toStub in interface javax.rmi.CORBA.PortableRemoteObjectDelegate

unexportObject

public void unexportObject(java.rmi.Remote obj)
                    throws java.rmi.NoSuchObjectException

This method is used to deregister a currently exported server object from the ORB runtimes, allowing the object to become available for garbage collection.

Specified by:

unexportObject in interface javax.rmi.CORBA.PortableRemoteObjectDelegate

narrow

public java.lang.Object narrow(java.lang.Object obj,
                               java.lang.Class newClass)
                        throws java.lang.ClassCastException

This method takes an object reference or an object of an RMI/IDL abstract interface type and attemps to narrow it to conform to the given newClass RMI/IDL type.

Specified by:

narrow in interface javax.rmi.CORBA.PortableRemoteObjectDelegate

uncheckedNarrow

public java.lang.Object uncheckedNarrow(java.lang.Object obj,
                                        java.lang.Class newClass)
                                 throws java.lang.ClassCastException

This method takes an object reference or an object of an RMI/IDL abstract interface type and attemps to narrow it to conform to the given newClass RMI/IDL type. This operation always succeeds, the

connect

public void connect(java.rmi.Remote target,
                    java.rmi.Remote source)
             throws java.rmi.RemoteException

This method makes the remote object target ready for remote communication using the same communications runtime as source.

Specified by:

connect in interface javax.rmi.CORBA.PortableRemoteObjectDelegate
