java.lang.Object

org.wildfly.swarm.topology.consul.runtime.CatalogWatcher

All Implemented Interfaces:

Runnable, org.jboss.msc.service.Service<CatalogWatcher>, org.jboss.msc.value.Value<CatalogWatcher>

public class CatalogWatcher
extends Object
implements org.jboss.msc.service.Service<CatalogWatcher>, Runnable

Catalog-watching service. This service regularly performs a blocking-wait poll of the catalog of all services in order to avoid having to know a-priori which services are of interest to the application. Any discovered service is setup with a related health-cache listener in order to maintain the full topology.
