Class TreatFn

public class TreatFn extends SystemFunction

This class supports the XPath 2.0 functions exactly-one(), one-or-more(), zero-or-one(). Because Saxon doesn't do strict static type checking, these are essentially identity functions; the run-time type checking is done as part of the function call mechanism

Method Summary
Item	evaluateItem(XPathContext context) Evaluate the function
String	getErrorCodeForTypeErrors() Return the error code to be used for type errors
SequenceIterator	iterate(XPathContext context) Iterate over the results of the function
