Method Detail

onThrowable

public void onThrowable(java.lang.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.

Parameters:

t - a Throwable

onBodyPartReceived

public AsyncHandler.State onBodyPartReceived(HttpResponseBodyPart bodyPart)
                                      throws java.lang.Exception

Invoked as soon as some response body part are received. Could be invoked many times. Beware that, depending on the provider (Netty) this can be notified with empty body parts.

Specified by:

onBodyPartReceived in interface AsyncHandler<T>

Parameters:

bodyPart - response's body part.

Returns:

a AsyncHandler.State telling to CONTINUE or ABORT the current processing. Aborting will also close the connection.

Throws:

java.lang.Exception - if something wrong happens

onStatusReceived

public AsyncHandler.State onStatusReceived(HttpResponseStatus responseStatus)
                                    throws java.lang.Exception

Specified by:

onHeadersReceived in interface AsyncHandler<T>

Parameters:

headers - the HTTP headers.
