Class Method Details

.call(object, file, destination_path) ⇒ Object

Persists the file within the object at destination_name. Uses basic containment. If you want to use direct containment (ie. with PCDM) you must use a different service (ie. Hydra::Works::AddFileToGenericFile Service)

Parameters:

  • object (Object) —

    the source file is attached to

  • filestream (File) —

    to be added, should respond to :mime_type, :original_name

  • destination_name (String) —

    is the fedora path at which the child resource will be found or created beneath the object.

Raises:

  • (NotImplementedError)
