Default is no name (the default exchange). .. attribute:: type *This description of AMQP exchange types was shamelessly stolen from the blog post `AMQP in 10 minutes: Part 4`_ by Rajith Attapattu. Reading this article is recommended if you're new to amqp.* "AMQP defines four default exchange types (routing algorithms) that covers most of the common messaging use cases. An AMQP broker can also define additional exchange types, so see your broker manual for more information about available exchange types. * `direct` (*default*) Direct match between the routing key in the message, and the routing criteria used when a queue is bound to this exchange. * `topic` Wildcard match between the routing key and the routing pattern specified in the exchange/queue binding. The routing key is treated as zero or more words delimited by `"."` and supports special wildcard characters. `"*"` matches a single word and `"#"` matches zero or more words. * `fanout` Queues are bound to this exchange with no arguments. Hence any message sent to this exchange will be forwarded to all queues bound to this exchange. * `headers` Queues are bound to this exchange with a table of arguments containing headers and values (optional). A special argument named "x-match" determines the matching algorithm, where `"all"` implies an `AND` (all pairs must match) and `"any"` implies `OR` (at least one pair must match). :attr:`arguments` is used to specify the arguments. .. _`AMQP in 10 minutes: Part 4`: http://bit.ly/amqp-exchange-types .. attribute:: channel The channel the exchange is bound to (if bound). .. attribute:: durable Durable exchanges remain active when a server restarts. Non-durable exchanges (transient exchanges) are purged when a server restarts. Default is :const:`True`. .. attribute:: auto_delete If set, the exchange is deleted when all queues have finished using it. Default is :const:`False`. .. attribute:: delivery_mode The default delivery mode used for messages. The value is an integer, or alias string. * 1 or `"transient"` The message is transient. Which means it is stored in memory only, and is lost if the server dies or restarts. * 2 or "persistent" (*default*) The message is persistent. Which means the message is stored both in-memory, and on disk, and therefore preserved if the server dies or restarts. The default value is 2 (persistent). .. attribute:: arguments Additional arguments to specify when the exchange is declared. ttdirecttnamettypet argumentstdurabletpassivet auto_deletet delivery_modecC@stj|ƒp|S(N(tDELIVERY_MODEStget(tm((s./tmp/pip-unpacked-wheel-UAnTfW/kombu/entity.pyt”RcK@sKtt|ƒj||p"|j|_|p4|j|_|j|ƒdS(N(tsuperRt__init__RRt maybe_bind(tselfRRtchanneltkwargs((s./tmp/pip-unpacked-wheel-UAnTfW/kombu/entity.pyR#—scC@std|jfƒS(NsE|%s(thashR(R%((s./tmp/pip-unpacked-wheel-UAnTfW/kombu/entity.pyt__hash__scC@sn|dkr|jn|}|jrj|jjd|jd|jd|jd|jd|jd|d|ƒSdS( sØDeclare the exchange.

Default is no name (default queue destination). .. attribute:: exchange The :class:`Exchange` the queue binds to. .. attribute:: routing_key The routing key (if any), also called *binding key*. The interpretation of the routing key depends on the :attr:`Exchange.type`. * direct exchange Matches if the routing key property of the message and the :attr:`routing_key` attribute are identical. * fanout exchange Always matches, even if the binding does not have a key. * topic exchange Matches the routing key property of the message by a primitive pattern matching scheme. The message routing key then consists of words separated by dots (`"."`, like domain names), and two special characters are available; star (`"*"`) and hash (`"#"`). The star matches any word, and the hash matches zero or more words. For example `"*.stock.#"` matches the routing keys `"usd.stock"` and `"eur.stock.db"` but not `"stock.nasdaq"`. .. attribute:: channel The channel the Queue is bound to (if bound). .. attribute:: durable Durable queues remain active when a server restarts. Non-durable queues (transient queues) are purged if/when a server restarts. Note that durable queues do not necessarily hold persistent messages, although it does not make sense to send persistent messages to a transient queue. Default is :const:`True`. .. attribute:: exclusive Exclusive queues may only be consumed from by the current connection. Setting the 'exclusive' flag always implies 'auto-delete'. Default is :const:`False`. .. attribute:: auto_delete If set, the queue is deleted when all consumers have finished using it. Last consumer can be cancelled either explicitly or because its channel is closed. If there was no consumer ever on the queue, it won't be deleted. .. attribute:: queue_arguments Additional arguments used when declaring the queue. .. attribute:: binding_arguments Additional arguments used when binding the queue. .. attribute:: alias Unused in Kombu, but applications can take advantage of this. For example to give alternate names to queues with automatically generated queue names. .. attribute:: on_declared Optional callback to be applied when the queue has been declared (the ``queue_declare`` operation is complete). This must be a function with a signature that accepts at least 3 positional arguments: ``(name, messages, consumers)``.
