Jobs in FixedUpdate

    When/where is JobHandle.Complete() actually called for all the jobs scheduled in JobComponentSystem.OnUpdate()?
    If I want all my jobs to run within the FixedUpdate cycle, do I need to create a JobComponentSystem to complete these myself or is it enough to tell Unity that this system updates after FixedUpdate?

    Code (CSharp):
    1. [UpdateAfter(UnityEngine.Experimental.PlayerLoop.FixedUpdate)]
    2. class JobSystemA{}
    4. [UpdateAfter(SystemA)]
    5. [UpdateAfter(UnityEngine.Experimental.PlayerLoop.FixedUpdate)]
    6. class JobSystemB{}
    8. [UpdateAfter(UnityEngine.Experimental.PlayerLoop.FixedUpdate)]
    9. [UpdateAfter(JobSystemB)]
    10. class EndFixedUpdateSystem{
    11.     OnUpdate(JobHandle inputDeps){
    12.         inputDeps.Complete();
    13.         return inputDeps;
    14.     }
    15. }

    Is EndFixedUpdateSystem necessary? My systems are running within FixedUpdate and the jobs are running but I'm not sure if they're running per Update or per FixedUpdate.

    Is the JobHandle passed into OnUpdate() the same handle returned from the previous JobComponentSystem?
