Constructor Summary

WithParam() Create a general variable

Method Summary
static void	displayExpressions(WithParam[] params, ExpressionPresenter out) DIsplay the parameter expressions
ValueRepresentation	evaluateVariable(XPathContext context) Evaluate the variable (method exists only to satisfy the interface)
int	getInstructionNameCode() Get the name of this instruction (that is xsl:variable, xsl:param etc) for diagnostics
int	getParameterId() Get the parameter id, which is essentially an alias for the parameter name, unique within a stylesheet
static void	getXPathExpressions(WithParam[] params, List list) Get the XPath expressions used in an array of WithParam parameters (add them to the supplied list)
static void	optimize(ExpressionVisitor visitor, WithParam[] params, ItemType contextItemType)
TailCall	processLeavingTail(XPathContext context)
static void	promoteParams(WithParam[] params, PromotionOffer offer) Promote the expressions in a set of with-param elements.
static boolean	replaceXPathExpression(WithParam[] params, Expression original, Expression replacement) Replace a subexpression
void	setParameterId(int id) Allocate a number which is essentially an alias for the parameter name, unique within a stylesheet
static void	simplify(WithParam[] params, ExpressionVisitor visitor)
static void	typeCheck(WithParam[] params, ExpressionVisitor visitor, ItemType contextItemType)
