bindVariable

public Expression bindVariable(StructuredQName qName)
                        throws XPathException

Description copied from class: IndependentContext

Bind a variable used in an XPath Expression to the XSLVariable element in which it is declared. This method is provided for use by the XPath parser, and it should not be called by the user of the API, or overridden, unless variables are to be declared using a mechanism other than the declareVariable method of this class.

Specified by:

bindVariable in interface StaticContext

Overrides:

bindVariable in class IndependentContext

Parameters:

qName - the name of the variable

Returns:

the resulting variable reference

Throws:

XPathException - if the variable cannot be bound (has not been declared)

allocateSlots

public void allocateSlots()
