public abstract class RemoteObject
extends Object
implements Remote, Serializable

The RemoteObject class implements the java.lang.Object behavior for remote objects. RemoteObject provides the remote semantics of Object by implementing methods for hashCode, equals, and toString.

RemoteObject(): Create a remote object.
RemoteObject(RemoteRef): Create a remote object, initialized with the specified remote reference.

equals(Object): Compares two remote objects for equality.
hashCode(): Returns a hashcode for a remote object.
toString(): Returns a String that represents the value of this remote object.

RemoteObject

 protected RemoteObject()

RemoteObject

 protected RemoteObject(RemoteRef newref)
