computeSpecialProperties()
Get the static properties of this expression (other than its type).

Item |
evaluateItem(XPathContext c)
Evaluate in a general context
|
int |
getIntrinsicDependencies()
Determine the dependencies
|
Expression |
preEvaluate(ExpressionVisitor visitor)
preEvaluate: this method suppresses compile-time evaluation by doing nothing
(because the value of the expression depends on the runtime context)
