/**
* The ServerContainer is the specialized view of the WebSocketContainer available in server-side deployments. There is
* one ServerContainer instance per websocket application. The ServerContainer holds the methods to be able to register
* server endpoints during the initialization phase of the application.
*
* For websocket enabled web containers, developers may obtain a reference to the ServerContainer instance by retrieving
* it as an attribute named javax.websocket.server.ServerContainer on the ServletContext. This way, the
* registration methods held on this interface may be called to register server endpoints from a ServletContextListener
* during the deployment of the WAR file containing the endpoint.
*
*
* WebSocket implementations that run outside the web container may have other means by which to provide a
* ServerContainer instance to the developer at application deployment time.
*
*
* Once the application deployment phase is complete, and the websocket application has begun accepting incoming
* connections, the registration methods may no longer be called.
