Method Detail

onStatusReceived

public final AsyncHandler.State onStatusReceived(HttpResponseStatus responseStatus)
                                          throws Exception

Description copied from interface: AsyncHandler

Invoked as soon as the HTTP status line has been received

Specified by:

onStatusReceived in interface AsyncHandler<NettyWebSocket>

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 final AsyncHandler.State onHeadersReceived(HttpResponseHeaders headers)
                                           throws Exception

Description copied from interface: AsyncHandler

Invoked as soon as the HTTP headers has been received. Can potentially be invoked more than once if a broken server sent trailing headers.

Specified by:

onHeadersReceived in interface AsyncHandler<NettyWebSocket>

Parameters:

headers - the HTTP headers.

Returns:

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

Throws:

Exception - if something wrong happens

onBodyPartReceived

public final AsyncHandler.State onBodyPartReceived(HttpResponseBodyPart bodyPart)
                                            throws Exception

Description copied from interface: AsyncHandler

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<NettyWebSocket>

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:

onCompleted

public final NettyWebSocket onCompleted()
                                 throws Exception

Returns:

T Value that will be returned by the associated Future

Throws:

Exception - if something wrong happens

onThrowable

public final void onThrowable(Throwable t)

Description copied from interface: AsyncHandler

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<NettyWebSocket>

Parameters:

t - a Throwable

setWebSocket

public final void setWebSocket(NettyWebSocket webSocket)

onOpen

public final void onOpen()
