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
