Interface for implementing proxies
There are no signals, because apparently Qt Plugins do not support interfaces, which inherit from QObject.
(it will fail upon loading the plugin)
You need to implement the following signals:
void process(std::string path); // called in a separate thread, has to block, will not be called again
void finished(); // thread finished and can be deleted
void error(QString err); // an error occured
void message(http::Flow flow); // a http::Flow was received
*/
class ProxyInterface {
public:
std::string path;
virtual ~ProxyInterface() = default;
//! called in a custom thread, may block.
virtual void process(std::string path) = 0;
//! returns, whether the proxy is currently connected
virtual bool connected() = 0;
//! disconnects the handle
virtual void disconnect() = 0;
// options/settings
std::function<void()> finished;
std::function<void(QString)> error;
std::function<void(http::Flow flow)> message;
};
