    • toSystemOut

      public static AgentBuilder.RedefinitionStrategy.Listener toSystemOut()
      Writes the stream result to System.out.
      Returns:

    • onBatch

      public void onBatch(int index, List<Class<?>> batch, List<Class<?>> types)
      Invoked before applying a batch.
      Specified by:
      onBatch in interface AgentBuilder.RedefinitionStrategy.Listener
      Parameters:
      index - A running index of the batch starting at 0.
      batch - The types included in this batch.
      types - All types included in the redefinition.
    • onError

      public Iterable<? extends List<Class<?>>> onError(int index, List<Class<?>> batch, Throwable throwable, List<Class<?>> types)
      Invoked upon an error during a batch. This method is not invoked if the failure handler handled this error.
      Specified by:
      onError in interface AgentBuilder.RedefinitionStrategy.Listener
