ErrorPolicy (documentapi 7.559.12 API)

java.lang.Object
- com.yahoo.documentapi.messagebus.protocol.ErrorPolicy

All Implemented Interfaces:

DocumentProtocolRoutingPolicy, com.yahoo.messagebus.routing.RoutingPolicy
```
public class ErrorPolicy
extends Object
implements DocumentProtocolRoutingPolicy
```
This policy assigns an error supplied at constructor time to the routing context when select(RoutingContext) is invoked. This is useful for returning error states to the client instead of those auto-generated by mbus when a routing policy can not be created.
