# Interface NodeSetData<T>

Type Parameters:
  `T` - the type of nodes maintained by this set

All Superinterfaces:
  `Data`, `Iterable<T>`

public interface NodeSetData<T> extends Data, Iterable<T>
An abstract representation of a `Data` type containing a node-set. The type (class) and ordering of the nodes contained in the set are not defined by this class; instead that behavior should be defined by `NodeSetData` subclasses.
