Method Details
- isValueNode
  
  public static boolean isValueNode(Object value)
  
  Returns true if the value is a ValueNode, such as a Record or ArrayValue.
- toJsonataData
  
  public static Object toJsonataData(Object value)
  
  Converts a DataPipeline ValueNode to a form the JSONata engine understands (Map, List, or plain Java value) without deep-copying.
  Record is wrapped in a JsonObject (implements Map), ArrayValue is wrapped in an JsonArray (implements List), and SingleValue is returned as its raw Java value.
- toValueNode
  
  public static ValueNode<?> toValueNode(Object value)
  
  Converts a JSONata engine result back to a DataPipeline ValueNode.
  If the result is already backed by a JsonObject or JsonArray, the original DataPipeline object is unwrapped directly — no copy required. Plain Map and List instances produced by the engine are converted to Record and ArrayValue respectively.
