NormalizeSpace

public NormalizeSpace()
Method Detail

simplify

public Expression simplify()
                    throws XPathException
Simplify and validate.

Specified by:
simplify in interface Expression
Overrides:
simplify in class FunctionCall
Throws:
XPathException

evaluateItem

public Item evaluateItem(XPathContext c)
                  throws XPathException
Evaluate in a general context

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

normalize

public static java.lang.String normalize(java.lang.String s)
The algorithm that does the work
