S - self return typepublic abstract class WebSocketImplBase<S extends WebSocketBase> extends Object implements WebSocketBase
The internal state is protected using the synchronized keyword. If always used on the same event loop, then we benefit from biased locking which makes the overhead of synchronized near zero.

public String binaryHandlerID()
WebSocketBaseWebSocket is created it automatically registers an event handler with the event bus - the ID of that
handler is given by this method.
Given this ID, a different event loop can send a binary frame to that event handler using the event bus and that buffer will be received by this instance in its own event loop and written to the underlying connection. This allows you to write data to other WebSockets which are owned by different event loops.

WebSocketBaseThis method should not be used to write application data and should only be used for implementing a keep alive or to ensure the client is still responsive, see RFC 6455 Section section 5.5.2.
There is no handler for ping frames because RFC 6455 clearly states that the only response to a ping frame is a pong frame with identical contents.

WebSocketBaseThis method should not be used to write application data and should only be used for implementing a keep alive or to ensure the client is still responsive, see RFC 6455 section 5.5.2.
There is no need to manually write a pong frame, as the server and client both handle responding to a ping from with a pong from automatically and this is exposed to users. RFC 6455 section 5.5.3 states that pongs may be sent unsolicited in order to implement a one way heartbeat.
