The hash of the data is computed while uploading, and
if the resulting object has a different hash, an attempt is made to delete the object.
Whether the deletion fails or not, an UploadValidationException
is thrown. If the deletion fails, that failure can be examined via
AdditionalFailures
None
The upload is not validated.
ThrowOnly
The hash of the data is computed while uploading, and
