org.openehealth.ipf.commons.ihe.fhir.FhirProvider

org.openehealth.ipf.commons.ihe.fhir.SharedFhirProvider

All Implemented Interfaces:

Serializable

Direct Known Subclasses:

BatchTransactionResourceProvider

public abstract class SharedFhirProvider
extends FhirProvider

Shared Resource provider, primarily (but not exclusively) meant for batch/transaction requests. Use this resource provider if you have several consumers that share the same FHIR interface. The request is dispatched to the first consumer that returns true on RequestConsumer.test(RequestDetails).

Components/Endpoints that use this resource provider must reference a (shared) singleton instance of a concrete implementation of this class.

Request consumers must share the same FhirContext instance.
