Interface FailureDetectorListener

public interface FailureDetectorListener

FailureDetectorListener is a simple means by which interested parties can listen for changes to the availability of nodes.

Note for implementors: Make sure that the FailureDetectorListener implementation properly implements the hashCode/equals methods to ensure adding and removing instances from the FailureDetector work as expected.
