goOffShift

Take the resource off-shift indefinitely. New seize requests wait in the request queue until goOnShift; in-flight allocations finish normally under the current ksl.modeling.entity.Resource.capacityChangeRule (IGNORE by default). Under IGNORE, a unit that is busy when this is called finishes its current allocation, and when it is released it goes to the off-shift change, not to the next waiting request. So a server that goes off shift mid-service finishes the customer in front of it and then stops.
