jdbc.IRISIterator.getSubscriptValue() gets the lowest level subscript for the node at the current iterator position. For example, if the iterator points to node ^myGlobal(23,"somenode"), the returned value will be "somenode".

Throws IllegalStateException if remove() has been called on the current node with this iterator, or there is no last element returned by this iterator (i.e. no successful next() or previous() calls).

String getSubscriptValue() throws IllegalStateException
