func (*Broker) AdjustRoutingKey

func (b *Broker) AdjustRoutingKey(s *tasks.Signature)

AdjustRoutingKey makes sure the routing key is correct. If the routing key is an empty string: a) set it to binding key for direct exchange type b) set it to default queue name

func (*Broker) CloseConnections

func (b *Broker) CloseConnections() error

func (*Broker) GetOrOpenConnection

func (b *Broker) GetOrOpenConnection(queueName string, queueBindingKey string, exchangeDeclareArgs, queueDeclareArgs, queueBindingArgs amqp.Table) (*AMQPConnection, error)

GetOrOpenConnection will return a connection on a particular queue name. Open connections are saved to avoid having to reopen connection for multiple queues

func (*Broker) Publish

func (b *Broker) Publish(signature *tasks.Signature) error

Publish places a new message on the default queue

func (*Broker) StartConsuming

func (b *Broker) StartConsuming(consumerTag string, concurrency int, taskProcessor iface.TaskProcessor) (bool, error)

StartConsuming enters a loop and waits for incoming messages

func (*Broker) StopConsuming

func (b *Broker) StopConsuming()

StopConsuming quits the loop
