All Implemented Interfaces:

org.cqframework.cql.cql2elm.LibrarySourceProvider, LibraryContentProvider

public class FhirClientFhirLibraryContentProvider
extends BaseFhirLibraryContentProvider

This class implements the LibraryContentProvider API, using a FHIR server as a source for Library resources containing CQL content. This class caches the Library resources that are resolved from the remote server, so it's intended to be short-lived (i.e. for the duration of a single CQL evaluation)
