DescendantIterator()
Create a DescendantIterator object.
|
| Modifier and Type | Method and Description |
|---|---|
int |
asNode(XPathContext xctxt)
Return the first node out of the nodeset, if this expression is
a nodeset expression.
|
DTMIterator |
cloneWithReset()
Get a cloned Iterator that is reset to the beginning
of the query.
|
boolean |
deepEquals(Expression expr)
Compare this object with another object and see
if they are equal, include the sub heararchy.
|
void |
detach()
Detaches the iterator from the set which it iterated over, releasing
any computational resources and placing the iterator in the INVALID
state.
|
int |
getAxis()
Returns the axis being iterated, if it is known.
|
int |
nextNode()
Returns the next node in the set and advances the position of the
iterator in the set.
|
void |
setRoot(int context,
java.lang.Object environment)
Initialize the context values for this expression
after it is cloned.
