## weblogic.rmi.extensions
Class PortableRemoteObject

    java.lang.Object
      weblogic.rmi.extensions.PortableRemoteObject

    public final class PortableRemoteObject

extends Object

API for managing references required by higher-level functionality. In particular we need to be able to narrow to IDL interfaces and create initial references. These functions mirror those in `PortableRemoteObject` but guarantee that the WebLogic versions will be called since users can replace the implementation of `PortableRemoteObject` themselves.

Constructor Summary
`PortableRemoteObject()`

Method Summary
`static void` | `exportObject(Remote obj)` Makes a server object ready to receive remote calls.
`static Object` | `narrow(Object narrowFrom, Class narrowTo)` Checks to ensure that an object of a remote or abstract interface type can be cast to a desired type.
`static Remote` | `toStub(Remote obj)` Returns a stub for the given server object.
`static void` | `unexportObject(Remote obj)` Deregisters a server object from the runtime, allowing the object to become available for garbage collection.

  Returns:
    the most derived stub for the object.
  Throws:
    `NoSuchObjectException` - if a stub cannot be located for the given server object.

### unexportObject

    public static void unexportObject(Remote obj)
                               throws NoSuchObjectException

  Deregisters a server object from the runtime, allowing the object to become available for garbage collection.

  Parameters:
    `obj` - the object to unexport.
  Throws:
    `NoSuchObjectException` - if the remote object is not currently exported.

### narrow

    public static Object narrow(Object narrowFrom,

                         throws ClassCastException

  Checks to ensure that an object of a remote or abstract interface type can be cast to a desired type.

  Parameters:
    `narrowFrom` - the object to check.
