The function called will be that of the object constructed so far, rather than a possibly overriding function in a derived class. This can be most confusing. Worse, a direct or indirect call to an unimplemented pure virtual function from a constructor or destructor results in undefined behavior....

然后简单地触发Call端口以激活您的模块,Cancel以中止它。 模块参数/端口 根据我们之前学到的知识,我们能够使用 void 端口调用模块。这在所有情况下都不是最佳选择,因为您可能希望向模块传递附加数据。 为了实现这一点,模块系统公开了模块参数。通过在流程图编辑器中选择工具 | 编辑模块...,我们可以为我们的模块添加...
