Example 2 with StaticQueryContext

use of net.sf.saxon.query.StaticQueryContext in project ph-schematron by phax.

the class XQueryAsXPathFunctionConverter method loadXQuery.

/**
 * Load XQuery functions from an input stream. As this function is supposed to
 * work with Saxon HE, this method allows only for loading full XQuery modules
 * and not for XQuery libraries.
 *
 * @param aXQueryIS
 *        The Input Stream to read from. May not be <code>null</code>. Will be
 *        closed automatically in this method.
 * @return A non-<code>null</code> {@link MapBasedXPathFunctionResolver}
 *         containing all loaded functions.
 * @throws XPathException
 *         if the syntax of the expression is wrong, or if it references
 *         namespaces, variables, or functions that have not been declared, or
 *         any other static error is reported.
 * @throws IOException
 *         if a failure occurs reading the supplied input.
