public abstract class RemoteObject extends Object implements Remote, Serializable
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.Modifier and Type | Field | Description |

Creates a remote object, initialized with the specified remote reference. |
Modifier and Type | Method | Description |

RemoteRef |
getRef() |
Returns the remote reference for the remote object. |
int |
hashCode() |
Returns a hashcode for a remote object. |
String |
toString() |
Returns a String that represents the value of this remote object. |
static Remote |
toStub |

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.
