---|---|---|
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.
|
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.

- The XPath runtime context for this

- The environment object.
The environment in which this iterator operates, which should provide:
At this time the exact implementation of this environment is application dependent. Probably a proper interface will be created fairly soon.
