Understanding parameters in onAfterCreate

[npastuh0v]

Colleagues, good afternoon. I'm analyzing a test case https://github.com/oatpp/example-yuv-websocket-stream . There are several questions:

1. In the signature of the method void onAfterCreate(const oatpp::websocket WebSocket& socket, const std::shared_ptr<const ParameterMap>& params) override; I am interested in the purpose of using the params attribute. I am interested in the route of passing this set of parameters: where does it come from and what kind of parameters can be contained there? I am interested in their practical significance. Maybe I didn't look through the documentation well, but I didn't see a description there. Thank you for your concern!
