* tune - propose connection tuning parameters
* tuneok - negotiate connection tuning parameters
* open - open connection to virtual host
* openok - signal that connection is ready
* close - request a connection close
* closeok - confirm a connection close

### Channel
work with channels

* open - open a channel for use
* openok - signal that the channel is ready
* close - request a channel close
* closeok - confirm a channel close

### Exchange 
work with exchanges

* declare - verify exchange exists, create if needed
* declareok - confirm exchange declaration
* delete - delete an exchange
* deleteok - confirm deletion of an exchange

### Queue 
work with queues 

* declare - declare queue, create if needed
* declareok - confirms a queue definition
* bind - bind queue to an exchange
* bindok - confirm bind successful
* unbind - unbind a queue from an exchange
* unbindok - confirm unbind successful
* purge - purge a queue
* purgeok - confirms a queue purge
* delete - delete a queue
* deleteok - confirm deletion of a queue

### Basic
work with basic content 

* qos - specify quality of service
* qosok - confirm the requested qos
* consume - start a queue consumer
* consumeok - confirm a new consumer
* publish - publish a message
* deliver - notify the client of a consumer message
* get - direct access to a queue
* getok - provide client with a message
* getempty - indicate no messages available
* ack - acknowledge one or more messages

Usage
------------

`Test::Test()
{
	QUrl con(QString("amqp://guest:guest@localhost:5672/"));
	client_ = new QAMQP::Client(this);
	client_->open(con);
	exchange_ =  client_->createExchange("test.test2");
	exchange_->declare("fanout");

	queue_ = client_->createQueue("test.my_queue", exchange_->channelNumber());
	queue_->declare();
	exchange_->bind(queue_);

	connect(queue_, SIGNAL(declared()), this, SLOT(declared()));
	connect(queue_, SIGNAL(messageRecieved()), this, SLOT(newMessage()));	

}

void Test::declared()
{
	exchange_->publish("Hello world", exchange_->name());
	queue_->setQOS(0,10);
	queue_->setConsumerTag("qamqp-consumer");
	queue_->consume(QAMQP::Queue::coNoAck);
}

void Test::newMessage()
{
	QAMQP::Queue * q = qobject_cast<QAMQP::Queue *>(sender());
	while (q->hasMessage())
	{
		QAMQP::MessagePtr message = q->getMessage();
		qDebug("+ RECEIVE MESSAGE");
		qDebug("| Exchange-name: %s", qPrintable(message->exchangeName));
		qDebug("| Routing-key: %s", qPrintable(message->routeKey));
		qDebug("| Content-type: %s", qPrintable(message->property[QAMQP::Frame::Content::cpContentType].toString()));
		if(!q->noAck())
		{
			q->ack(message);
		}
	}
