- Method Detail
  - onWebSocketClose
```
void onWebSocketClose(int statusCode,
                      java.lang.String reason)
```
    A Close Event was received.
    The underlying Connection will be considered closed at this point.
    
    Parameters:
    
    statusCode - the close status code. (See StatusCode)
    
    reason - the optional reason for the close.
  - onWebSocketConnect
```
void onWebSocketConnect(Session session)
```
    A WebSocket Session has connected successfully and is ready to be used.
    Note: It is a good idea to track this session as a field in your object so that you can write messages back via the RemoteEndpoint
    
    Parameters:
    
    session - the websocket session.
  - onWebSocketError
```
void onWebSocketError(java.lang.Throwable cause)
```
    A WebSocket exception has occurred.
    This is a way for the internal implementation to notify of exceptions occurred during the processing of websocket.
    Usually this occurs from bad / malformed incoming packets. (example: bad UTF8 data, frames that are too big, violations of the spec)
    This will result in the Session being closed by the implementing side.
    
    Parameters:
    
    cause - the error that occurred.
