HttpException - in case of HTTP protocol violation

IOException - in case of an I/O error

consumeContent

public final void consumeContent(ContentDecoder decoder,
                                 IOControl ioctrl)
                          throws IOException

Use onContentReceived(ContentDecoder, IOControl) instead.

Specified by:

consumeContent in interface HttpAsyncRequestConsumer<T>

Parameters:

decoder - content decoder.

ioctrl - I/O control of the underlying connection.

Throws:

IOException - in case of an I/O error

requestCompleted

public final void requestCompleted(HttpContext context)

Use buildResult(HttpContext) instead.

Specified by:

requestCompleted in interface HttpAsyncRequestConsumer<T>

Parameters:

context - HTTP context

failed

public final void failed(Exception ex)

Description copied from interface: HttpAsyncRequestConsumer

Invoked to signal that the request processing terminated abnormally.

Specified by:

failed in interface HttpAsyncRequestConsumer<T>

Parameters:

ex - exception

close

public final void close()
                 throws IOException

Specified by:

close in interface Closeable

Specified by:

close in interface AutoCloseable

Throws:

IOException

getException

public Exception getException()

Description copied from interface: HttpAsyncRequestConsumer

Returns an exception in case of an abnormal termination. This method returns null if the request execution is still ongoing or if it completed successfully.

Specified by:

getException in interface HttpAsyncRequestConsumer<T>

See Also:

HttpAsyncRequestConsumer.isDone()

getResult

public T getResult()

Description copied from interface: HttpAsyncRequestConsumer

Returns a result of the request execution, when available. This method returns null if the request execution is still ongoing.

Specified by:

getResult in interface HttpAsyncRequestConsumer<T>

See Also:

HttpAsyncRequestConsumer.isDone()

isDone

public boolean isDone()

Description copied from interface: HttpAsyncRequestConsumer

Determines whether or not the request execution completed. If the request processing terminated normally HttpAsyncRequestConsumer.getResult() can be used to obtain the result. If the request processing terminated abnormally HttpAsyncRequestConsumer.getException() can be used to obtain the cause.

Specified by:
