  • Method Details

    • convertToAxiomValue

      Y convertToAxiomValue(X value)

      Parameters:
      value - Value to convert
      Returns:
      Converted data

    • convertToAttribute

      X convertToAttribute(Y value)
      Converts the data stored in the repository into the value to be stored in the entity attribute.

      Note that it is the responsibility of the converter writer to specify the correct value type for the corresponding value for use by the OntoDriver: i.e., persistence providers are not expected to do such type conversion.

      Parameters:
      value - Value to convert
      Returns:
      Converted data
