public interface Liveness
extends java.rmi.Remote

Defines the basic liveness interface to which all deployed components respond.

Method Summary

void	sfPing(java.lang.Object source) Check liveness of component.

Method Detail

sfPing

void sfPing(java.lang.Object source)
            throws SmartFrogLivenessException,
                   java.rmi.RemoteException

Check liveness of component. Any exception while executing this call should mean that the component has failed. Since multiple sources can call on a component, the source of the liveness message is also passed in

Parameters:

source - Source of call. Optional; can be null.

Throws:

SmartFrogLivenessException - liveness failure

java.rmi.RemoteException - In case of Remote/nework error
