      • registerClassLoadCallback

        public static void registerClassLoadCallback​(java.lang.String className,
                                             java.lang.Runnable callback)
        Register a callback to run when a class is loading.

        Caveats:

        • This callback will be invoked by a jvm class transformer.
        • Classes filtered out by AgentInstaller's skip list will not be matched.
        Parameters:
        className - name of the class to match against
        callback - runnable to invoke when class name matches
