Method Details

isValidBlobId

public boolean isValidBlobId(String theNewBlobId)

This implementation prevents: \ / | .

Specified by:

isValidBlobId in interface IBinaryStorageSvc

Overrides:

isValidBlobId in class BaseBinaryStorageSvcImpl

Parameters:

theNewBlobId - the blob ID to validate

Returns:

true if the blob ID is valid, false otherwise.

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

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.

theRequestDetails - The operation request details.

Returns:

Returns details about the stored data

Throws:

IOException

fetchBlobDetails

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

Throws:

IOException

writeBlob

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

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)

fetchBlob

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

Description copied from interface: IBinaryStorageSvc

Fetch the contents of the given blob

Parameters:

theResourceId - The resource ID

theBlobId - The blob ID

Returns:

The payload as a byte array

Throws:

IOException
