Item |
evaluateItem(XPathContext c) |
Evaluate the expression
|
int |
getIntrinsicDependencies() |
Determine the dependencies
|
SequenceIterator |
iterate(XPathContext c) |
Return an iteration over the result sequence
|
Expression |
preEvaluate(StaticContext env) |
preEvaluate: this method suppresses compile-time evaluation by doing nothing
(because the value of the expression depends on the runtime context)
