• startok - select security mechanism and locale
• 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); } } }`
