Class RemoteObject

    • Field Detail

      • ref

        protected transient RemoteRef ref
        The object's remote reference.
    • Constructor Detail

      • RemoteObject

        protected RemoteObject()
        Creates a remote object.
      • RemoteObject

        protected RemoteObject(RemoteRef newref)
        Creates a remote object, initialized with the specified remote reference.
        Parameters:
        newref - remote reference
    • Method Detail

      • getRef

        public RemoteRef getRef()
        Returns the remote reference for the remote object.

        Note: The object returned from this method may be an instance of an implementation-specific class. The RemoteObject class ensures serialization portability of its instances' remote references through the behavior of its custom writeObject and readObject methods. An instance of RemoteRef should not be serialized outside of its RemoteObject wrapper instance or the result may be unportable.

        Returns:
        remote reference for the remote object
        Since:
        1.2
      • toStub

        public static Remote toStub(Remote obj)
                             throws NoSuchObjectException
        Returns the stub for the remote object obj passed as a parameter. This operation is only valid after the object has been exported.
        Parameters:
        obj - the remote object whose stub is needed
        Returns:
        the stub for the remote object, obj.
        Throws:
        NoSuchObjectException - if the stub for the remote object could not be found.
        Since:
        1.2
      • hashCode

        public int hashCode()
        Returns a hashcode for a remote object. Two remote object stubs that refer to the same remote object will have the same hash code (in order to support remote objects as keys in hash tables).
        Overrides:
        hashCode in class Object
        Returns:
        a hash code value for this object.
        See Also:
        Hashtable
      • equals

        public boolean equals(Object obj)
        Compares two remote objects for equality. Returns a boolean that indicates whether this remote object is equivalent to the specified Object. This method is used when a remote object is stored in a hashtable. If the specified Object is not itself an instance of RemoteObject, then this method delegates by returning the result of invoking the equals method of its parameter with this remote object as the argument.
        Overrides:
        equals in class Object
        Parameters:
        obj - the Object to compare with
        Returns:
        true if these Objects are equal; false otherwise.
        See Also:
        Hashtable
      • toString

        public String toString()
        Returns a String that represents the value of this remote object.
        Overrides:
        toString in class Object
        Returns:
        a string representation of the object.
