      • canHandle

        public static boolean canHandle​(java.lang.Class<?> classLoaderClass,
                                LogNode log)
        Check whether this ClassLoaderHandler can handle a given ClassLoader.
        Parameters:
        classLoaderClass - the ClassLoader class or one of its superclasses.
        log - the log
        Returns:
        true if this ClassLoaderHandler can handle the ClassLoader.

      • findClassLoaderOrder

        public static void findClassLoaderOrder​(java.lang.ClassLoader classLoader,
                                        ClassLoaderOrder classLoaderOrder,
                                        LogNode log)
        Find the ClassLoader delegation order for a ClassLoader.
        Parameters:
        classLoader - the ClassLoader to find the order for.
        classLoaderOrder - a ClassLoaderOrder object to update.
        log - the log

      • getPaths

        private static java.util.Collection<java.lang.Object> getPaths​(java.lang.Object containerClassLoader,
                                                               ReflectionUtils reflectionUtils)
        Get the paths from a containerClassLoader object.

        The passed in object should be an instance of "com.ibm.ws.classloading.internal.ContainerClassLoader".

        Will attempt to use "getContainerURLs" methods to recap the classpath.

        Parameters:
        containerClassLoader - the containerClassLoader object
        Returns:
        Collection of path objects as a URL or String.
