                              HttpException
        Invoked when a HTTP response message is received. Please note that the consumeContent(ContentDecoder, IOControl) method will be invoked only if the response messages has a content entity enclosed.
        Parameters:
        response - HTTP response message.

      • consumeContent

        void consumeContent​(ContentDecoder decoder,
                            IOControl ioctrl)
                     throws java.io.IOException
        Invoked to process a chunk of content from the ContentDecoder. The IOControl interface can be used to suspend input event notifications if the consumer is temporarily unable to process content.

        The consumer can use the ContentDecoder.isCompleted() method to find out whether or not the message content has been fully consumed.

        Please note that the ContentDecoder object is not thread-safe and should only be used within the context of this method call. The IOControl object can be shared and used on other thread to resume input event notifications when the consumer is capable of processing more content.

        Parameters:
        decoder - content decoder.
        ioctrl - I/O control of the underlying connection.
        Throws:
        java.io.IOException - in case of an I/O error
