5.14.4 Command: 0x0309 (reject message transfers)
Signature: reject( options: map, first: sequence-no, last: sequence-no, reject-properties: map )
The reject command is used to indicate that incoming messages are invalid and therefore unprocessable. Any
message whose first incoming transfer falls within the specified incoming command range is considered
rejected. Continuation transfers within the rejection range are ignored. For this command to have any effect,
it MUST be sent before the identified transfers are acknowledged. If an attempt to transfer a message results
in a reject from the recipient, the sender should add the supplied reject-properties to the message header, and
make the message available at an alternative node (e.g. a dead letter queue).
Field Details:
options: map
options map (optional)
first: sequence-no
(required)
The start of the incoming command range.
last: sequence-no
(optional)
The end of the incoming command range. If not set then this is taken to be the same as first.
reject-properties: map
(optional)
The map supplied in this field will be placed in any rejected message headers under the key
"reject-properties".
