ref
protected transient RemoteRef ref
- the object's remote reference
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
getRef
public RemoteRef getRef()
- Returns the remote reference for the remote object.
- 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 java.lang.Object
- See Also:
Hashtable
equals
public boolean equals(java.lang.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 java.lang.Object
- Parameters:
obj
- the Object to compare with- Returns:
- true if these Objects are equal; false otherwise.
