Class ServiceRestarter

java.lang.Object

org.apache.brooklyn.core.objs.AbstractBrooklynObject

org.apache.brooklyn.core.objs.AbstractEntityAdjunct

org.apache.brooklyn.core.policy.AbstractPolicy

org.apache.brooklyn.policy.ha.ServiceRestarter

All Implemented Interfaces:

Rebindable, BrooklynObject, Configurable, EntityAdjunct, Identifiable, Policy, BrooklynObjectInternal

public class ServiceRestarter
extends AbstractPolicy

attaches to a SoftwareProcess (or anything Startable, emitting ENTITY_FAILED or other configurable sensor), and invokes restart on failure; if there is a subsequent failure within a configurable time interval, or if the restart fails, this gives up and emits ENTITY_RESTART_FAILED
