Do subscribers work on a FIFO queue?
Do the queues used in ros::Subscriber behave like FIFO queues?
In particular, if I use a message_filters::Synchronizer that, in approximately equal time increments, invokes a callback function for a subscribed topic with queue size 1000. Will the queue items (passed to the callback) be processed in FIFO order?
