ServiceRestarter (Apache Brooklyn)

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
