Module amqp_selective_consumer

This module is an implementation of the amqp_gen_consumer behaviour and can be used as part of the Consumer parameter when opening AMQP channels.

Behaviours: amqp_gen_consumer.

Description

This module is an implementation of the amqp_gen_consumer behaviour and can be used as part of the Consumer parameter when opening AMQP channels. This is the default implementation selected by channel.

The Consumer parameter for this implementation is {amqp_selective_consumer, []}
This consumer implementation keeps track of consumer tags and sends the subscription-relevant messages to the registered consumers, according to an internal tag dictionary.

Send a #basic.consume{} message to the channel to subscribe a consumer to a queue and send a #basic.cancel{} message to cancel a subscription.

The channel will send to the relevant registered consumers the basic.consume_ok, basic.cancel_ok, basic.cancel and basic.deliver messages received from the server.

If a consumer is not registered for a given consumer tag, the message is sent to the default consumer registered with amqp_selective_consumer:register_default_consumer. If there is no default consumer registered in this case, an exception occurs and the channel is abruptly terminated.

Function Index

register_default_consumer/2This function registers a default consumer with the channel.

Function Details

register_default_consumer/2

register_default_consumer(ChannelPid, ConsumerPid) -> ok

This function registers a default consumer with the channel. A default consumer is used when a subscription is made via amqp_channel:call(ChannelPid, #'basic.consume'{}) (rather than amqp_selective_consumer:subscribe/3) and hence there is no consumer pid registered with the consumer tag. In this case, the relevant deliveries will be sent to the default consumer.
