Interface ExceptionHook

public interface ExceptionHook

Allows implementors to control how certain exceptions should be handled.

This interface is intended to be implemented for multi-master setups to control the behavior for handling exceptions that are thrown by a lower layer that handles the consensus and synchronization between different server nodes. E.g. if an operation fails because consensus for a Git update could not be achieved (e.g. due to slow responding server nodes) this interface can be used to retry the request instead of failing it immediately.
