我们可以创建一个CallbackCaller类的实例,并注册我们在上一步中定义的回调函数。然后,通过调用do_something方法,触发回调函数的执行。以下是一个示例代码: if__name__=="__main__":caller=CallbackCaller()caller.register_callback(callback_function)caller.register_callback(CallbackClass.callback_method)caller...

MyClass类中包含了一个event实例,用于处理事件回调。通过调用event.register(callback)方法,可以将回调函数注册到事件中。在do_something方法中,当某个条件满足时,调用event.fire(data)方法触发事件,并将相关数据传递给回调函数。 事件回调在许多场景中都有广泛的应用,例如图形界面编程、网络编程、异步编程等。它可以...
Originally, I implemented the class with a callback function I passed to the object during initialization. This callback is invoked whenever a solution is found. In looking at someone else's implementation of the same problem, I saw that they were using yield statements to pass a solution ...
keras中是通过各种回调函数来实现钩子hook功能的。这里放一个callback的父类,定制时只要继承这个父类,实现你过关注的钩子就可以了。 @keras_export('keras.callbacks.Callback')classCallback(object):"""Abstract base class used to build new callbacks.Attributes:params: Dict. Training parameters(eg. verbosity...
