/**
 * 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 {@link io.vertx.ext.consul.Watch original} non RX-ified interface using Vert.x codegen.
