Properties

Name	Type	Description
name	string	The name of the exchange. The empty string denotes the default (nameless) direct exchange.
type	string	The exchange type which determines the routing algorithm.

autoDelete	boolean	If true, the exchange is automatically deleted when the last queue is unbound from it.
internal	boolean	If true, the exchange cannot be directly published to by clients; it can only receive messages from other exchanges via exchange-to-exchange bindings.
arguments	object	Optional arguments for exchange declaration, used for broker-specific extensions (e.g., alternate exchange).
