 # IteratableToNodeConverter
 
-**Important**: By default empty nodes get not serialized. NullNode forces null value serialization.

- * ArrayNode (no elements)
- * BoolNode (null)
- * ObjectNode (no elements)
- * FloatNode (null)
- * IntNode (null)
- * StringNode (null)

-This works recursive, which means theoretically a multidimensional array can lead into an empty string return.

-Check the `allowSerializeEmpty` argument to prevent this if needed.
