Class SetNode

java.lang.Object
  org.loom.binding.Node
      org.loom.binding.SetNode

public class SetNode
extends Node

Node that corresponds with a Set property. Set properties cannot be traversed. Since there is no way to identify a concrete node inside a Set, property paths like child.friends[1].name are not allowed if friends is a Set (since there is no way to use the index in any meaningful way). Sets can be used to identify "bags of things", provided that these are simple objects (Strings, Integers, etc) and are tipically handled by inputCheckbox tags.
