Method Detail

onThrowable

public void onThrowable(Throwable t)

Invoked when an unexpected exception occurs during the processing of the response. The exception may have been produced by implementation of onXXXReceived method invocation.

Specified by:

onThrowable in interface AsyncHandler<WebSocket>

Parameters:

t - a Throwable

touchSuccess

public boolean touchSuccess()

resetSuccess

public void resetSuccess()

onBodyPartReceived

public AsyncHandler.STATE onBodyPartReceived(HttpResponseBodyPart bodyPart)
                                      throws Exception

Invoked as soon as some response body part are received. Could be invoked many times.

Specified by:

onBodyPartReceived in interface AsyncHandler<WebSocket>

Parameters:

bodyPart - response's body part.

Returns:

a AsyncHandler.STATE telling to CONTINUE or ABORT the current processing.

Throws:

Exception - if something wrong happens

onStatusReceived

public AsyncHandler.STATE onStatusReceived(HttpResponseStatus responseStatus)
                                    throws Exception

Invoked as soon as the HTTP status line has been received

Specified by:

onStatusReceived in interface AsyncHandler<WebSocket>

Parameters:

responseStatus - the status code and test of the response

Returns:

a AsyncHandler.STATE telling to CONTINUE or ABORT the current processing.

Throws:

Exception - if something wrong happens

onHeadersReceived

public AsyncHandler.STATE onHeadersReceived(HttpResponseHeaders headers)
                                     throws Exception

Returns:

T Value that will be returned by the associated Future

Throws:

Exception - if something wrong happens

onSuccess

public void onSuccess(WebSocket webSocket)

If the HTTP Upgrade succeed (response's status code equals 101), the AsyncHttpProvider will invoke that method

Specified by:

onSuccess in interface UpgradeHandler<WebSocket>

Parameters:

onFailure

public void onFailure(Throwable t)

If the upgrade fail.

Specified by:

onFailure in interface UpgradeHandler<WebSocket>
