public class RRCCTypesDiscoverer
extends Object
implements org.gcube.informationsystem.model.knowledge.TypesDiscoverer<org.gcube.informationsystem.types.reference.Type>

TypesDiscoverer backed by a ResourceRegistrySchemaClientImpl: discovers types by fetching them directly from the Resource Registry server (bypassing any local cache), so that TypesKnowledge can bootstrap or renew its own cache from an authoritative source.
