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.

Method Details

storeBlob

public StoredDetails storeBlob(org.hl7.fhir.instance.model.api.IIdType theResourceId,
 String theBlobIdOrNull,
 String theContentType,
 InputStream theInputStream)
                        throws IOException

Description copied from interface: IBinaryStorageSvc

Store a new binary blob

Specified by:

storeBlob in interface IBinaryStorageSvc

Parameters:

theResourceId - The resource ID that owns this blob. Note that it should not be possible to retrieve a blob without both the resource ID and the blob ID being correct.

theBlobIdOrNull - If set, forces

theContentType - The content type to associate with this blob

theInputStream - An InputStream to read from. This method should close the stream when it has been fully consumed.

Returns:

Returns details about the stored data

Throws:

IOException

fetchBlobDetails

public StoredDetails fetchBlobDetails(org.hl7.fhir.instance.model.api.IIdType theResourceId,
 String theBlobId)

Specified by:

fetchBlobDetails in interface IBinaryStorageSvc

writeBlob

public boolean writeBlob(org.hl7.fhir.instance.model.api.IIdType theResourceId,
 String theBlobId,
 OutputStream theOutputStream)
                  throws IOException

Specified by:

writeBlob in interface IBinaryStorageSvc

Returns:

Returns true if the blob was found and written, of false if the blob was not found (i.e. it was expunged or the ID was invalid)

Throws:

IOException

expungeBlob

public void expungeBlob(org.hl7.fhir.instance.model.api.IIdType theResourceId,
 String theBlobId)

Specified by:

expungeBlob in interface IBinaryStorageSvc

fetchBlob

public byte[] fetchBlob(org.hl7.fhir.instance.model.api.IIdType theResourceId,
 String theBlobId)

Description copied from interface: IBinaryStorageSvc

Fetch the contents of the given blob

Specified by:

fetchBlob in interface IBinaryStorageSvc

Parameters:

theResourceId - The resource ID

theBlobId - The blob ID

Returns:

The payload as a byte array

clear

public void clear()
