Interface FailoverSupport<T,E extends Exception>

All Known Implementing Classes:

FailoverNoopSupport, FailoverRetrySupport

public interface FailoverSupport<T,E extends Exception>

FailoverSupport defines an interface for different types of fail-over handlers, that provide different types of behaviour for handling fail-overs during operations that can be interrupted by the fail-over process. For example, the support could automatically retry once the fail-over process completes, could prevent an operation from being started whilst fail-over is running, or could quietly abandon the operation or raise an exception, and so on.

TODO Continuation, extend some sort of re-usable Continuation interface, which might look very like this one.
