        public RuleLoader findLoader​(Digester d,
                                     java.lang.Class pluginClass,
                                     java.util.Properties p)
                              throws PluginException
        If there exists on the plugin class a method with name matching the constructor's methodName value then locate the appropriate Method on the plugin class and return an object encapsulating that info.

        If there is no matching method then just return null.

        The returned object (when non-null) will invoke the target method on the plugin class whenever its addRules method is invoked. The target method is expected to have the following prototype: public static void xxxxx(Digester d, String patternPrefix);
