public class CacheAwareModelManager
extends org.cqframework.cql.cql2elm.ModelManager

This class extends the CQL translator ModelManager class to be aware of a global cache of Models The global cache is by @{org.hl7.elm.r1.VersionedIdentifier}, while the local cache is by name. This is because the translator expects the ModelManager to only permit loading of a single version version of a given Model in a single translation context, while the global cache is for all versions of Models
