Member Function Documentation

Get()

virtual std::string urabbitmq::IChannelInterface::Get ( const Queue & queue, utils::Flags< Queue::Flags > flags, engine::Deadline deadline )

pure virtual

Gets a single message.

You should to set kNoAck flag in order for server to implicitly acknowledge gathered message. By default the gathered message has to be explicitly acknowledged or rejected, however there's no functionality for that yet, so the flag is basically mandatory. This API is a subject to change.

Note

This method uses a polling model for retrieving a message, which is comparatively expensive and might lead to a connection reset in case of a timeout. This method could come in handy in some cases, but in general we recommend to set up a Consumer instead.

Parameters

queue	name of the queue
flags	queue flags
deadline	execution deadline

Implemented in urabbitmq::Channel, and urabbitmq::Client.

Publish() [1/2]

virtual void urabbitmq::IChannelInterface::Publish ( const Exchange & exchange, const std::string & routing_key, const std::string & message, engine::Deadline deadline )

pure virtual

overload of Publish

Implemented in urabbitmq::Channel, and urabbitmq::Client.

Publish() [2/2]

virtual void urabbitmq::IChannelInterface::Publish ( const Exchange & exchange, const std::string & routing_key, const std::string & message, MessageType type, engine::Deadline deadline )

pure virtual

Publish a message to an exchange.

You have to supply the name of the exchange and a routing key. RabbitMQ will then try to send the message to one or more queues. By default unroutable messages are silently discarded

Parameters

exchange	the exchange to publish to
routing_key	the routing key
message	the message to send
deadline	execution deadline

Note

This method is fire and forget (no delivery guarantees), use PublishReliable for delivery guarantees.

Implemented in urabbitmq::Channel, and urabbitmq::Client.
