ExtendedDataRule Interface

Rule used to inject some extended data into presentation data objects (nodes, records).

A couple of typical use cases:

  • Table is showing models and elements polymorphically and application wants to handle all models and all elements differently. The rule can be used to inject some flag that tells whether table row represents a model or an element.
  • Tree shows a hierarchy of models and elements. Then element node is clicked, application needs to additionally know element model's ID. The rule can be used to inject that ID into element's node.
