public class FitsUpdateListener
extends AbstractRmiListener
implements RmiUpdateListener, Reloadable

A helper class that allows this parameter to benefit from RMI-enabled data transfer. Cannot be a inner class of RemoteSensorStub due to rmic-problems.

Field Detail

data

private UpdateListener data

The data value reference that is served by this rmi-data listener.

Constructor Detail

FitsUpdateListener

protected FitsUpdateListener(Map<String,String> info)
                      throws RemoteException

Constructs a new helper class that is responsible for listener surveying.

Throws:

RemoteException

Method Detail

rescanned

public double rescanned(String key,
                        String old,
                        String newval)

Makes this method public, no further changes.

Specified by:

rescanned in interface Reloadable

Overrides:

rescanned in class AbstractRmiListener

registerAtCaster

protected boolean registerAtCaster(RmiCaster caster,
                                   Class ignore)

Checks if the rmi-caster is a rmi data caster. If so this, stub registers to it as a data listener.

Specified by:

registerAtCaster in class AbstractRmiListener

Returns:

True, if this listener can register at the specified caster

deregisterAtCaster

protected boolean deregisterAtCaster(RmiCaster caster,
                                     Class ignore)

Checks if the rmi-caster is a rmi data caster. If so this, stub deregisters from it as a data listener.

Specified by:

deregisterAtCaster in class AbstractRmiListener

Returns:

True, if this listener can deregister at the specified caster

setUpdateListener

protected void setUpdateListener(UpdateListener serve)

Sets the DataValue class that receives this rmi data events.

rmiUpdated

public void rmiUpdated()
                throws RemoteException

Receives a remote data event from a weather sensor.

Specified by:

rmiUpdated in interface RmiUpdateListener

Throws:

RemoteException
