Examples of client.net.sf.saxon.ce.expr.Expression

Interface supported by an XPath expression. This includes both compile-time and run-time methods.
Two expressions are considered equal if they return the same result when evaluated in the same context.

     * if all the arguments are constant; functions that do not require this behavior
     * can override the preEvaluate method.
