    • beforeRead

      String beforeRead(Model model, String source, OntDocumentManager odm)

      Behaviour that is invoked before the contents of the given source (URI or filename) are read into the given model. The return value from this method denotes a revised string to use in place of the supplied source string. Handlers are permitted to make state changes to the model and the ODM, but carefully!

      Parameters:
      model - The model that is going to receive the contents of the source
      source - The identity of the source, as a file name or URI
      odm - The Ont Document Manager invoking this handler
      Returns:
      The revised name of the source (or the same string if no change to the source is required). Note that if this method returns null, the source will not be subsequently read.

    • afterRead

      void afterRead(Model model, String source, OntDocumentManager odm)

      Behaviour that is invoked just after the contents of the given source (URI or filename) have been read into the given model. Handlers are permitted to make state changes to the model and the ODM, but carefully!

      Parameters:
