Event ordering is a part of the event registry meant to sort the future events.
It is especially important to manage simultaneous events. These events does not exists in the real life, but the.
Date ordering
Date ordering is sorting events by date
It could be done with compare-field on the date field of the event (typically ::sim-engine/date)
Simultaneous event ordering
A simultaneous event ordering apply user defined decision on which event should be executed first
It could leverage compare-types and compare-field or what user defined functions
Simultaneous events
Two or more events are simultaneous if they happen at the same date in the scheduler.

compare-fieldclj/s
(compare-field field)Returns a function to compare e1 and e2 based on values of field field. nil values are accepted.
Returns a function to compare `e1` and `e2` based on values of field `field`. `nil` values are accepted.
compare-typesclj/s
(compare-types evt-type-priorities)Compares two events e1 and e2 with their types, based on their ordering in evt-type-priorities, list of event priorities, ordered with higher priority first in the list.
Returns the difference of their position in the evt-type-priorities, which is 0 in case of equality, negative if e1 is before e2.
Compares two events `e1` and `e2` with their types, based on their ordering in `evt-type-priorities`, list of event priorities, ordered with higher priority first in the list. Returns the difference of their position in the `evt-type-priorities`, which is `0` in case of equality, negative if `e1` is before `e2`.

(sorter orderings)Returns a function with two events as parameters and returning the comparison of them, according to event-orderings.
Returns a function with two events as parameters and returning the comparison of them, according to event-orderings.
