      java.lang.Object convertDataValueToObjectValue​(java.lang.Object fieldValue, Session session)
      INTERNAL: The field value must first be converted to the field type, then the attribute type.
      java.lang.Object convertObjectValueToDataValue​(java.lang.Object attributeValue, Session session)
      INTERNAL: Convert to the field class.
      java.lang.Class getDataClass()
      PUBLIC: Returns the class type of the data value.
      java.lang.String getDataClassName()
      INTERNAL: Return the name of the data type for the MW usage.
      protected DatabaseMapping getMapping()
      INTERNAL: Return the mapping.

      PUBLIC: Returns the class type of the object value.
      java.lang.String getObjectClassName()
      INTERNAL: Return the name of the object type for the MW usage.
      void initialize​(DatabaseMapping mapping, Session session)
      INTERNAL: Set the mapping.
      boolean isMutable()
      INTERNAL: If the converter converts the value to a non-atomic value, i.e.
      void setDataClass​(java.lang.Class dataClass)
      PUBLIC: Set the class type of the data value.
      void setDataClassName​(java.lang.String dataClassName)
      INTERNAL: Set the name of the data type for the MW usage.
      void setObjectClass​(java.lang.Class objectClass)
      PUBLIC: Set the class type of the object value.

      • convertClassNamesToClasses

        public void convertClassNamesToClasses​(java.lang.ClassLoader classLoader)
        INTERNAL: Convert all the class-name-based settings in this converter to actual class-based settings. This method is used when converting a project that has been built with class names to a project with classes. This method is implemented by subclasses as necessary.
