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.
Returns a read-only iterator over the nodes contained in this
NodeSetData in
document order. Attempts to modify the returned iterator
via the remove method throw
UnsupportedOperationException.
