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.
Field Summary | |
---|---|
protected transient RemoteRef |
ref
The object's remote reference. |
Constructor Summary | |

protected |
Creates a remote object. |

RemoteObject(RemoteRef newref) Creates a remote object, initialized with the specified remote reference. |
Method Summary | |
---|---|
boolean |
Compares two remote objects for equality. |
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 |
Returns the stub for the remote object obj passed
as a parameter.

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.
