通过多个功能发送任意数据 [英] Sending arbitrary data through several functions

问题描述

在制作遵循状态设计模式（正在工作的状态）时的状态系统到目前为止相当不错），我现在想知道是否有办法发送任意数据到这个系统。我认为这可能是使用刺激类。

While making a state system that follows the state design pattern (which is working quite well so far) and I am now wondering if there is a way to send arbitrary data to this system. I was thinking that this might be possible using a Stimulus class.

系统本身被合成到另一个可以响应刺激的对象，而状态机和国家自己也可以有刺激，他们将通过功能调用从外层传递到内层。问题是刺激需要将这些数据带入这些不同的层次，我不能想到一个简单的方法来解决它。

The system itself is composited into another object that can respond to the stimuli, and both the state machine and the states themselves can have stimuli as well, and they will be passed from the outer to the inner levels via function calls. The problem being that the stimuli need to carry arbitrary data to these different levels, and I can't think of a simple way to get it out.

我在想可能使用 dynamic_cast ，但我想知道是否有更好的方法。
