Method Detail

evaluateItem

public Item evaluateItem(XPathContext c)
                  throws XPathException

Evaluate the function

Specified by:

evaluateItem in interface Expression

Overrides:

evaluateItem in class ComputedExpression

Parameters:

c - 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

escape

public static java.lang.CharSequence escape(java.lang.CharSequence s,
                                            boolean escapeReserved)
