从 SequenceWaiter 获取事件对象

Question

当我将 SequenceWaiter 步骤添加到 SequenceRunner 中时，如何获取传递到事件中的事件对象？我的测试函数中有代码：

var sequence: SequenceRunner = new SequenceRunner(this);
sequence.addStep(new SequenceCaller(manager, function(): void {
    manager.startUpload();
}));
sequence.addStep(new SequenceWaiter(manager, PackageUploadEvent.BEFORE_PACKAGE_UPLOAD, 1000));
sequence.addStep(new SequenceCaller(manager, function(): void {
    // TODO: Get event object from PackageUploadEvent.BEFORE_PACKAGE_UPLOAD event
}));

在flexunit 论坛上回答。基本思想是扩展SequenceWaiter类，重写setupListeners函数来设置额外的事件监听器，并将事件对象保存到该监听器的公共字段中。
