ca.uhn.fhir.jpa.binary.svc.BaseBinaryStorageSvcImpl
ca.uhn.fhir.jpa.binstore.MemoryBinaryStorageSvcImpl
- All Implemented Interfaces:
IBinaryStorageSvc
public class MemoryBinaryStorageSvcImpl
extends BaseBinaryStorageSvcImpl
implements IBinaryStorageSvc
Purely in-memory implementation of binary storage service. This is really
only appropriate for testing, since it doesn't persist anywhere and is
limited by the amount of available RAM.

storeBlob
@Nonnull public StoredDetails storeBlob(org.hl7.fhir.instance.model.api.IIdType theResourceId, String theBlobIdOrNull, String theContentType, InputStream theInputStream, ca.uhn.fhir.rest.api.server.RequestDetails theRequestDetails) throws IOException Description copied from interface:IBinaryStorageSvc
Store a new binary blob- Specified by:
storeBlob
in interfaceIBinaryStorageSvc
- Parameters:
