Item |
evaluateItem(XPathContext c)
Evaluate in a general context
|
int |
getIntrinsicDependencies()
Determine the dependencies
|
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)
