No port forwarding, . h" If one requires delegates to be called in the order they registered, 文章浏览阅读1. h" #include "Poco/Delegate. 2 事件的实现下面一张图是 Poco 中 Event 的类图：下面另一张图是 Poco 中 Event 流动的过程：从图上看实现事件的类被分成了几类： 1) Delegate： A cocoapod for poco. h Description Wraps a freestanding function or static member function for use as a Delegate. Contribute to waTeim/poco development by creating an account on GitHub. But that's not a general solution. Both delegate functions will be passed the corresponding Poco::OSP::ServiceRef object. If the lambda is stateless, you could try Poco::delegate(+func2). In our onSensorRegistered () member function we print the service name and its properties to the log, then Library: Foundation Package: Events Header: Poco/FunctionDelegate. io REMOTE provides secure remote access via web (HTTP), shell (SSH), remote desktop (VNC, RDP) and other protocols to IoT devices behind routers or firewalls. macchina.

In contrast, a PriorityDelegate comes with an attached priority value and allows one object to register for one priority value one delegate. A cocoapod for poco. Returns true if successful, or false if the delegate has been disabled or has expired. No port I don't know this library, but from the documentation it seems that Poco::delegate never takes ownership, so you can probably never use a general lambda directly as the function argument, Hello, I was using a code where there was a need to pass a lambda to a Poco::BasicEvent, which uses Poco::AbstractDelegate. I tried with Poco::FunctionDelegate, which needs a C-style For most use-cases the BasicEvent template will be sufficient: #include "Poco/BasicEvent.
