Queue Modes (Ordering Disciplines)

Selecting a Queue Mode will affect the way that incoming items are ordered into the group of waiting items.

First In First Out
The first item to enter the queue is the first to leave. Items queue behind each other in the order they have arrived. This is the default for a queue.

Last In First Out
Later items leave earliest. The last item to enter the queue is the first to leave. Items entering the queue move in front of existing items in the queue.

Highest Priority First
Higher priority items are put first. (Priority is an attribute ot the item that can be set when editing the item, or altered in a change object routine).

Lowest Priority First
Items entering the queue go in front of other items which have a lower item priority than themselves.
Highest Attribute First
Items with a higher value for a selected Item Attribute are put first.

Lowest Attribute First
Items with a lower value for a selected Item Attribute are put first.
