getSpecialProperties
Get the static properties of this expression (other than its type). The result is bit-significant. These properties are used for optimizations. In general, if property bit is set, it is true, but if it is unset, the value is unknown.- Overrides:
getSpecialProperties
in classSystemFunction
- Parameters:
arguments
- the actual arguments to the function call- Returns:
- the properties
-
getIdrefMultiple
public static SequenceIterator getIdrefMultiple(TreeInfo doc, SequenceIterator keys, XPathContext context) throws XPathException Get the result when multiple idref values are supplied. Note this is also called from compiled XQuery code.- Parameters:
doc
- the document to be searchedkeys
- the idref values suppliedcontext
- the dynamic execution context- Returns:
- iterator over the result of the function
- Throws:
XPathException
- if a dynamic error occurs
-
call
Evaluate the expression- Parameters:
context
- the dynamic evaluation contextarguments
- the values of the arguments, supplied as SequenceIterators- Returns:
- the result of the evaluation, in the form of a SequenceIterator
- Throws:
XPathException
- if a dynamic error occurs during the evaluation of the expression
