Class LocalParam

public final class LocalParam extends GeneralVariable

The compiled form of an xsl:param element in the stylesheet or an external variable in a Query.
The xsl:param element in XSLT has mandatory attribute name and optional attribute select. It can also be specified as required="yes" or required="no". In standard XQuery external variables are always required, and no default value can be specified; but Saxon provides an extension pragma that allows a query to specify a default.

Method Summary
ValueRepresentation	evaluateVariable(XPathContext c) Evaluate the variable
int	getInstructionNameCode() Get the name of this instruction for diagnostic and tracing purposes
Iterator	iterateSubExpressions() Get all the XPath expressions associated with this instruction (in XSLT terms, the expression present on attributes of the instruction, as distinct from the child instructions in a sequence construction)
TailCall	processLeavingTail(XPathContext context) Process the local parameter declaration
void	setConversion(Expression convertor) Define a conversion that is to be applied to the supplied parameter value.
