Interface ExceptionHandler

public interface ExceptionHandler

If NATS detects a serious problem with a Connection object, it informs the Connection object's ExceptionHandler, if one has been registered. It does this by calling the listener's onException method, passing it a NATSException argument describing the problem.

An exception handler allows a client to be notified of a problem asynchronously. Some connections only consume messages asynchronously, so they would have no other way to learn that their connection has failed.
