Class Watch<T>

java.lang.Object
io.vertx.rxjava3.ext.consul.Watch<T>
All Implemented Interfaces:
io.vertx.lang.rx.RxDelegate
public class Watch<T> extends Object implements io.vertx.lang.rx.RxDelegate
Watches are a way of specifying a view of data (e.g. list of nodes, KV pairs, health checks) which is monitored for updates. When an update is detected, an Handler with WatchResult is invoked. All errors, except java.util.concurrent.TimeoutException, will be handled, with resubscribing with a progressive delay. All timeout errors will be ignored, with resubscribing without any delay. As an example, you could watch the status of health checks and notify when a check is critical.

NOTE: This class has been automatically generated from the original non RX-ified interface using Vert.x codegen.
