JobComponentSystem.Entities with static helper method.

Hi. I have a question about new JobComponentSystem.Entities and its usage in static helper method.

Is it safe to use JobComponentSystem.Entities in other static method? like this:

static class MyQueryFactory
{
    public static ForEachLambdaJobDescription CreateCommonQuery(ForEachLambdaJobDescription entities, ref int paramForCapture)
    {

        return entities.ForEach(...); // capture paramForCapture in lambda
    }
}

class MySystem : JobComponentSystem
{
    JobHandle Update(JobHandle inputDeps)
    {
        int localValue = 3;

        return MyQueryFactory.CreateCommonQuery(this.Entities, ref localValue).Schedule(inputDeps);
    }
}

Thanks.

Seems like all of those attempts fall into this error:

error DC0011: Every Entities.ForEach statement needs to end with a .Schedule(), .ScheduleParallel() or .Run() invocation.

It would be nice to have this so we could reuse all those jobs without having to write the same/similar lambda expression over and over again.

Yes, I definitively want to be able to create static utilities function, did you manage to find a way to do it ?

The same problem occurs when using SystemBase

Same issue when trying to go for extension methods.

Best bet is for the utility method to rely on IJob or IJobChunk I guess.

Could allowing extension methods in the Entities method chain be implemented in the next Entities release?
