19.2. AMQ 0-10 Message Property Keys

The Qpid Messaging API recognizes special message property keys and automatically provides a mapping to their corresponding AMQP 0-10 definitions.

For example, when sending a message, if the properties contain an entry for x-amqp-0-10.app-id, its value will be used to set the message-properties.app-id property in the outgoing message. Likewise, if an incoming message has message-properties.app-id set, its value can be accessed via the x-amqp-0-10.app-id message property key.

Similarly, when sending a message, if the properties contain an entry for x-amqp-0-10.content-encoding, its value will be used to set the message-properties.content-encoding property in the outgoing message. Likewise, if an incoming message has message-properties.content-encoding set, its value can be accessed via the x-amqp-0-10.content-encoding message property key.

The routing key (delivery-properties.routing-key) in an incoming messages can be accessed via the x-amqp-0-10.routing-key message property.
