Method Details

getName

public String getName()

Specified by:

getName in interface ProtocolHandler

Returns:

a unique name among protocol handlers

accept

public boolean accept(Request request,
 Response response)

Description copied from interface: ProtocolHandler

Inspects the given request and response to detect whether this protocol handler should handle them.

For example, a redirect protocol handler can inspect the response code and return true if it is a redirect response code.

This method is being called just after the response line has been parsed, and before the response headers are available.

Specified by:

accept in interface ProtocolHandler

Parameters:

request - the request to accept

response - the response to accept

Returns:

true if this protocol handler can handle the given request and response

getResponseListener

public Response.Listener getResponseListener()

Specified by:

getResponseListener in interface ProtocolHandler

Returns:

a response listener that will handle the request and response on behalf of the application.

onHeader

public boolean onHeader(Response response,
 HttpField field)

Description copied from interface: Response.HeaderListener

Callback method invoked when a response header has been received and parsed, returning whether the header should be processed or not.

Specified by:

onHeader in interface Response.HeaderListener

Specified by:

onHeader in interface Response.Listener

Parameters:

response - the response containing the response line data and the headers so far

field - the header received

Returns:

true to process the header, false to skip processing of the header

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
