      Returns:
      the transformed value

    • traverseMap

      protected Object traverseMap(JsonValue value)
      Transform a JsonValue Map into another object. Default implementation is to return a new LinkedHashMap filled with the elements on which we applied the transformations.
      Parameters:
      value - the value to transform
      Returns:
      the transformed value
