  - getTransportType
```
public TransportType getTransportType()
```
    Description copied from interface: TransportHandler
    Return the transport type supported by this handler.
  - getContentType
```
protected MediaType getContentType()
```
    Specified by:
    getContentType in class AbstractHttpSendingTransportHandler
  - checkSessionType
```
public boolean checkSessionType(SockJsSession session)
```
    Description copied from interface: TransportHandler
    Check whether the type of the given session matches the transport type of this TransportHandler where session id and the transport type are extracted from the SockJS URL.
    Returns:
    true if the session matches (and would therefore get accepted by TransportHandler.handleRequest(org.springframework.http.server.ServerHttpRequest, org.springframework.http.server.ServerHttpResponse, org.springframework.web.socket.WebSocketHandler, org.springframework.web.socket.sockjs.transport.SockJsSession)), or false otherwise
  - createSession
```
public StreamingSockJsSession createSession(String sessionId,
                                            WebSocketHandler handler,
                                            Map<String,Object> attributes)
```
    Description copied from interface: SockJsSessionFactory
    Create a new SockJS session.
    Parameters:
    sessionId - the ID of the session
    handler - the underlying WebSocketHandler
    attributes - handshake request specific attributes
    Returns:
    a new session, never null
  - handleRequestInternal
```
public void handleRequestInternal(ServerHttpRequest request,
                                  ServerHttpResponse response,
                                  AbstractHttpSockJsSession sockJsSession)
                           throws SockJsException
```
    Overrides:
    handleRequestInternal in class AbstractHttpSendingTransportHandler
    Throws:
    SockJsException
  - getFrameFormat
