|---|---|
| pack-priv | OneStepIterator(Compiler
A reference to the Compiler that contains the op map. compiler, int The position within the op map, which contains the
location path expression for this itterator. opPos, int analysis)Create a OneStepIterator object. |
| public | OneStepIterator(DTMAxisIterator
The DTM iterator which this iterator will use. iterator, int One of Axis.Child, etc., or -1 if the axis is unknown. axis)Create a OneStepIterator object. |
| Modifier and Type | Method and Description |
|---|---|
| public Object | Returns: A new iterator that can be used without mutating this one.Overrides com. Implements com. Get a cloned iterator. |
| public DTMIterator | Returns: A cloned NodeIterator set of the start of the query.Overrides com. Implements com. Get a cloned Iterator that is reset to the beginning of the query. |
| protected void | countProximityPosition(int
The predicate index. i)Overrides com. Count backwards one proximity position. |
| public boolean | deepEquals(Expression
Another expression object. expr)Overrides com. Compare this object with another object and see if they are equal, include the sub heararchy. |
| public void | detach()
Overrides com. Implements com. Detaches the iterator from the set which it iterated over, releasing any computational resources and placing the iterator in the INVALID state. |
| public int | Returns: Axis.CHILD, etc., or -1 if the axis is not known or is of multiple types.Overrides com. Implements com. Returns the axis being iterated, if it is known. |
| public int | Returns: The number of nodes in the list, always greater or equal to zero.Overrides com. Implements com. The number of nodes in the list. |
| protected int | getNextNode()
Overrides com. Get the next node via getFirstAttribute && getNextAttribute. |
| protected int | Returns: The pridicate index, or -1.The predicate index of the proximity position. predicateIndex)Overrides com. Get the current sub-context position. |
| public boolean | Returns: true for this class.Overrides com. Tells if this is a reverse axes. |
| public void | reset()
Overrides com. Implements com. Reset the iterator. |
| public void | setRoot(int
The XPath runtime context for this
transformation. context, Object The environment object.
The environment in which this iterator operates, which should provide:
environment)
At this time the exact implementation of this environment is application dependent. Probably a proper interface will be created fairly soon. Overrides com. Implements com. Initialize the context values for this expression after it is cloned. |

| protected int getProximityPosition(int predicateIndex) Overrides com. Get the current sub-context position. In order to do the reverse axes count, for the moment this re-searches the axes up to the predicate. An optimization on this is to cache the nodes searched, but, for the moment, this case is probably rare enough that the added complexity isn't worth it.
