      • bind

        java.lang.ClassLoader bind​(boolean usePrivilegedAction,
                           java.lang.ClassLoader originalClassLoader)
        Change the current thread context class loader to the web application class loader. If no web application class loader is defined, or if the current thread is already using the web application class loader then no change will be made. If the class loader is changed and a ThreadBindingListener is configured then ThreadBindingListener.bind() will be called after the change has been made.
        Parameters:
        usePrivilegedAction - Should a PrivilegedAction be used when obtaining the current thread context class loader and setting the new one?
        originalClassLoader - The current class loader if known to save this method having to look it up
        Returns:
        If the class loader has been changed by the method it will return the thread context class loader in use when the method was called. If no change was made then this method returns null.

      • unbind

        void unbind​(boolean usePrivilegedAction,
            java.lang.ClassLoader originalClassLoader)
        Restore the current thread context class loader to the original class loader in used before bind(boolean, ClassLoader) was called. If no original class loader is passed to this method then no change will be made. If the class loader is changed and a ThreadBindingListener is configured then ThreadBindingListener.unbind() will be called before the change is made.
        Parameters:
        usePrivilegedAction - Should a PrivilegedAction be used when setting the current thread context class loader?
