short |
acceptNode(int n,
XPathContext xctxt)
Test whether a specified node is visible in the logical view of a
TreeWalker or NodeIterator.
|
void |
detach()
Detaches the iterator from the set which it iterated over, releasing
any computational resources and placing the iterator in the INVALID
state.
|
protected int |
getNextNode()
Get the next node via getNextXXX.
|
int |
nextNode()
Returns the next node in the set and advances the position of the
iterator in the set.
|
void |
setRoot(int context,
Object environment)
Initialize the context values for this expression
after it is cloned.

At this time the exact implementation of this environment is application dependent. Probably a proper interface will be created fairly soon.
