Examples of net.sf.saxon.functions.FunctionLibrary

net.sf.saxon.functions.FunctionLibrary
A FunctionLibrary handles the binding of function calls in XPath (or XQuery) expressions. There are a number of implementations of this class to handle different kinds of function: system functions, constructor functions, vendor-defined functions, Java extension functions, stylesheet functions, and so on. There is also an implementation {@link net.sf.saxon.functions.FunctionLibraryList} that allows a FunctionLibraryto be constructed by combining other FunctionLibrary objects.

        // We need to remove the default XPathFunctionLibrary to replace it
        // with our own
        List libList = ((FunctionLibraryList)getFunctionLibrary()).libraryList;
        XPathFunctionLibrary xpathLib = null;
        for (Object lib : libList) {
            FunctionLibrary flib = (FunctionLibrary) lib;
            if (flib instanceof XPathFunctionLibrary) xpathLib = (XPathFunctionLibrary) flib;
        }
        if (xpathLib != null) libList.remove(xpathLib);
        OdeXPathFunctionLibrary oxpfl = new OdeXPathFunctionLibrary(funcResolver);
        oxpfl.setXPathFunctionResolver(funcResolver);
