public abstract class BasicTestIterator
extends LocPathIterator

Base for iterators that handle predicates. Does the basic next node logic, so all the derived iterator has to do is get the next node.

Method Detail

### nextNode

    public int nextNode()

  Returns the next node in the set and advances the position of the iterator in the set. After a NodeIterator is created, the first call to nextNode() returns the first node in the set.
  Returns:
    The next `Node` in the set being iterated over, or `null` if there are no more members in that set.
  Overrides:
    nextNode in class LocPathIterator

### cloneWithReset

    public DTMIterator cloneWithReset()
                               throws java.lang.CloneNotSupportedException

  Get a cloned Iterator that is reset to the beginning of the query.
  Returns:
    A cloned NodeIterator set of the start of the query.
  Throws:
    java.lang.CloneNotSupportedException -
  Overrides:
    cloneWithReset in class LocPathIterator
