Interface java.rmi.server.RemoteRef

public interface RemoteRef

extends Externalizable

packagePrefix

Find server package prefix: assumes that the implementation of server ref classes (e.g., UnicastRef, UnicastServerRef) are located in the package defined by the prefix.

done(RemoteCall)

Allows the remote reference to clean up (or reuse) the connection.

getRefClass(ObjectOutput)

Returns the class name of the ref type to be serialized onto the stream 'out'.

invoke(RemoteCall)

Executes the remote call.

newCall(RemoteObject, Operation[], int, long)

Creates an appropriate call object for a new remote method invocation on this object.

remoteEquals(RemoteRef)

Compares two remote objects for equality.

remoteHashCode()

Returns a hashcode for a remote object.

remoteToString()

Returns a String that represents the reference of this remote object.

Properties Public Constant 
    packagePrefix=String 

Find server package prefix: assumes that the implementation of server ref classes (e.g., UnicastRef, UnicastServerRef) are located in the package defined by the prefix.

    method newCall(obj=RemoteObject, -
                   op=Operation[], -
                   opnum=int, -
                   hash=long) returns RemoteCall public abstract    Signals RemoteException

Creates an appropriate call object for a new remote method invocation on this object. Passing operation array and index, allows the stubs generator to assign the operation indexes and interpret them. The remote reference may need the operation to encode in the call.

Throws: RemoteException

if registry could not be contacted.

    method invoke(call=RemoteCall)  public abstract    Signals Exception

Executes the remote call. Invoke will raise any "user" exceptions which should pass through and not be caught by the stub. If any exception is raised during the remote invocation, invoke should take care of cleaning up the connection before raising the "user" or remote exception.

Throws: Exception

if a general exception occurs.

    method done(call=RemoteCall)  public abstract    Signals RemoteException

Allows the remote reference to clean up (or reuse) the connection. Done should only be called if the invoke returns successfully (non-exceptionally) to the stub.

Throws: RemoteException

if registry could not be contacted.

    method getRefClass(out=ObjectOutput) returns String public abstract    

Returns the class name of the ref type to be serialized onto the stream 'out'.

    method remoteHashCode() returns int public abstract    

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).

See Also:

Hashtable

    method remoteEquals(obj=RemoteRef) returns boolean public abstract    

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.

Parameters:

obj - the Object to compare with

Returns:

true if these Objects are equal; false otherwise.

See Also:

Hashtable

    method remoteToString() returns String public abstract    

Returns a String that represents the reference of this remote object.
