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.- See Also:

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.- Specified by:
nextNode
in interfaceDTMIterator
- Specified by:
nextNode
in classLocPathIterator
- Returns:
- The next
Node
in the set being iterated over, ornull
if there are no more members in that set.
-
cloneWithReset
public DTMIterator cloneWithReset() throws java.lang.CloneNotSupportedException
Get a cloned Iterator that is reset to the beginning of the query.- Specified by:
cloneWithReset
in interfaceDTMIterator
- Overrides:
cloneWithReset
in classLocPathIterator
- Returns:
- A cloned NodeIterator set of the start of the query.
- Throws:
java.lang.CloneNotSupportedException
