A simple loop over the array would be fine (this also avoids the Set allocation)
Wrapping in
Set.of
is useful only if the same command object is passed in more than once, which should be rare or even nonexistent.Note that a variadic argument will always create a new array, even if no objects are passed in; ie,
isScheduled()
effectively compiles toisScheduled(new Command[0])
, so this approach doesn't prevent array allocations. If you want to avoid array object allocations, overloads for some number of predetermined parameter counts would be necessary.There was a problem hiding this comment.

That loop would make it match the C++ version too.

Is it worth doing the predetermined overloads? multi-command schedule checks are already uncommon

A single-command overload would probably be fine with varargs as a fallback
