Method Detail

evaluateItem

public Item evaluateItem(XPathContext context)
                  throws XPathException
Evaluate the expression

Specified by:
evaluateItem in interface Expression
Overrides:
evaluateItem in class ComputedExpression
Parameters:
context - The context in which the expression is to be evaluated
Returns:
the node or atomic value that results from evaluating the expression; or null to indicate that the result is an empty sequence
Throws:
XPathException - if any dynamic error occurs evaluating the expression

deepEquals

public static boolean deepEquals(NodeInfo n1,
                                 NodeInfo n2,
                                 AtomicComparer collator)
                          throws XPathException
Determine whether two nodes are deep-equal

Throws:
XPathException
