Examples of XPathVariable

net.sf.saxon.sxpath.XPathVariable
An object representing an XPath variable for use in the standalone XPath API. The object can only be created by calling the declareVariable method of class {@link IndependentContext}. Note that once declared, this object is thread-safe: it does not hold the actual variable value, which means it can be used with any number of evaluations of a given XPath expression, in series or in parallel.
A variable can be given a value by calling {@link XPathDynamicContext#setVariable(XPathVariable,net.sf.saxon.om.ValueRepresentation)}. Note that the value of the variable is not held in the XPathVariable object, but in the XPathDynamicContext, which means that the XPathVariable itself can be used in multiple threads.
