Method Details

onBegin

public void onBegin(Response serverResponse)

Description copied from interface: Response.BeginListener

Callback method invoked when the response line containing HTTP version, HTTP status code and reason has been received and parsed.

This method is the best approximation to detect when the first bytes of the response arrived to the client.

Specified by:

onBegin in interface Response.BeginListener

Specified by:

onBegin in interface Response.Listener

Parameters:

serverResponse - the response containing the response line data

onHeaders

public void onHeaders(Response serverResponse)

Description copied from interface: Response.HeadersListener

Callback method invoked when all the response headers have been received and parsed.

Specified by:

onHeaders in interface Response.HeadersListener

Specified by:

onHeaders in interface Response.Listener

Parameters:

serverResponse - the response containing the response line data and the headers

onContent

public void onContent(Response serverResponse,
 Content.Chunk chunk,
 Runnable demander)

Description copied from interface: Response.AsyncContentListener

Callback method invoked when the response content has been received, parsed and there is demand. The chunk must be consumed, copied, or retained before returning from this method as it is then automatically released. The demander must be run before this method may be invoked again.

Specified by:

onContent in interface Response.AsyncContentListener

Specified by:

onContent in interface Response.ContentListener

Parameters:

serverResponse - the response containing the response line data and the headers

chunk - the chunk received

demander - the runnable to be run to demand the next chunk

onSuccess

public void onSuccess(Response serverResponse)

Description copied from interface: Response.SuccessListener

Callback method invoked when the whole response has been successfully received.

Specified by:

onSuccess in interface Response.Listener

Specified by:

onSuccess in interface Response.SuccessListener

Parameters:

serverResponse - the response containing the response line data and the headers

onComplete

public void onComplete(Result result)

Description copied from interface: Response.CompleteListener

Callback method invoked when the request and the response have been processed, either successfully or not.

The result parameter contains the request, the response, and eventual failures.

Requests may complete after response, for example in case of big uploads that are discarded or read asynchronously by the server. This method is always invoked after Response.SuccessListener.onSuccess(Response) or Response.FailureListener.onFailure(Response, Throwable), and only when request indicates that it is completed.

Specified by:

onComplete in interface Response.CompleteListener

Specified by:

onComplete in interface Response.Listener

Parameters:

result - the result of the request / response exchange

succeeded

public void succeeded()

Description copied from interface: Callback

Callback invoked when the operation completes.

Specified by:

succeeded in interface Callback

See Also:

• Callback.failed(Throwable)

failed

public void failed(Throwable failure)

Description copied from interface: Callback

Callback invoked when the operation fails.

Specified by:

failed in interface Callback

Parameters:

failure - the reason for the operation failure
