public abstract class EntityCreatedObserver<E>
extends Object

Base observer class used to build a JAX-RS response when creating an entity (metric, tenant, ...).

On failure, a 409 CONFLICT response is built if the exception indicates the resource already exists, otherwise a 500 SERVER ERROR reponse is built.
