    • toManifest

      public Node toManifest(Document document, MediaPackageSerializer serializer) throws MediaPackageException
      Description copied from interface: ManifestContributor
      This method returns an XML serialization of the object to be stored in the media package manifest. It should be possible to reconstruct the object from this data.

      For creating MediaPackageElements from a manifest, please use MediaPackageElementBuilder.elementFromManifest(org.w3c.dom.Node, MediaPackageSerializer). All other objects shall provide their own implementation specific reconstruction mechanism.

      Specified by:
      toManifest in interface ManifestContributor
      Overrides:
      toManifest in class AbstractMediaPackageElement
      Parameters:
      document - the parent
      serializer - the media package serializer

      the object's xml representation
      Throws:
      MediaPackageException - if the mediapackage can't be serialized
