evaluate
public AtomicValue evaluate(Item item, XPathContext context) throws XPathException
Description copied from class:ScalarSystemFunctionAbstract method that must be supplied in subclasses to perform the evaluation- Specified by:
evaluatein classScalarSystemFunction- Parameters:
item- the supplied argumentcontext- the dynamic context- Returns:
- the result of the evaluation
- Throws:
XPathException- if a dynamic error occurs
-
nodeName

getCompilerName
public java.lang.String getCompilerName()
Description copied from class:SystemFunctionGet the (local) name of a class that can be used to generate bytecode for this system function- Overrides:
getCompilerNamein classSystemFunction- Returns:
- the name of a bytecode generation class, or null if there is no bytecode support for this function
