Class BindingInfo

java.lang.Object

org.acemq.rabbitmq.admin.BindingInfo

public final class BindingInfo
extends Object

A binding: the rule joining an exchange to a queue or to another exchange.

Invisible to AMQP entirely. There is no way to ask a broker what is bound to what, which is why a topology plan over AMQP reports every binding as a creation and why "nothing is bound for this routing key" is discovered by publishing and being refused.

Constructor Details

BindingInfo

public BindingInfo(String source,
 String vhost,
 String destination,
 String destinationType,
 String routingKey,
 Map<String,Object> arguments,
 String propertiesKey)

Method Details

source

public String source()

Returns:

the exchange messages come from. Empty for the implicit binding every queue has to the default exchange under its own name, which is not a binding anybody made and cannot be removed

vhost

public String vhost()

destination

public String destination()

Returns:

the queue or exchange messages go to

destinationType

public String destinationType()

Returns:

queue or exchange

routingKey

public String routingKey()

Returns:

the routing key or pattern

arguments

public Map<String,Object> arguments()

Returns:

the binding arguments, which is where a headers exchange keeps its matching rules

isDefaultExchangeBinding

public boolean isDefaultExchangeBinding()

Returns:

whether this is the unremovable default-exchange binding rather than a real one

propertiesKey

public String propertiesKey()

The broker's identifier for this binding, needed to delete it.

A binding has no name. Several may join the same pair of objects with different routing keys and arguments, so the delete URL identifies one by this key rather than by anything a caller chose.

It arrives already percent-encoded. A routing key of a.# has a properties key of a.%23, and it belongs in the URL exactly as given — encoding it again produces a.%2523, which matches nothing and 404s. This is why RabbitAdmin.unbind(BindingInfo) takes the whole object rather than a routing key: reconstructing this string correctly is not something a caller should have to know about.

Returns:

the properties key, or null if the broker did not send one

toString

public String toString()

Overrides:

toString in class Object
