WriteBuffer.Sink	Interface implemented by clients of the WriteBuffer to enable data to be written back out from the buffer.
WsContainerProvider
WsContextListener	In normal usage, this ServletContextListener does not need to be explicitly configured as the WsSci performs all the necessary bootstrap and installs this listener in the ServletContext.
WsExtension
WsExtensionParameter
WsFilter	Handles the initial HTTP connection for WebSocket connections.
WsFrameBase	Takes the ServletInputStream, processes the WebSocket frames it contains and extracts the messages.
WsFrameBase.ReadState	WAITING - not suspended Server case: waiting for a notification that data is ready to be read from the socket, the socket is registered to the poller Client case: data has been read from the socket and is waiting for data to be processed PROCESSING - not suspended Server case: reading from the socket and processing the data Client case: processing the data if such has already been read and more data will be read from the socket SUSPENDING_WAIT - suspended, a call to suspend() was made while in WAITING state.
WsFrameClient
WsFrameServer
WsHandshakeRequest	Represents the request that this session was opened under.

WsPongMessage
WsRemoteEndpointAsync
WsRemoteEndpointBase
WsRemoteEndpointBasic
WsRemoteEndpointImplBase
WsRemoteEndpointImplClient
WsRemoteEndpointImplServer	This is the server side RemoteEndpoint implementation - i.e. what the server uses to send data to the client.
WsSci	Registers an interest in any class that is annotated with ServerEndpoint so that Endpoint can be published via the WebSocket server.
WsServerContainer	Provides a per class loader (i.e. per web application) instance of a ServerContainer.
WsSession
WsSessionListener
WsWebSocketContainer
WsWriteTimeout	Provides timeouts for asynchronous web socket writes.
