CombineDependencies(NativeArray) behavior

Couldn’t find this documented anywhere, so…

Is it necessary to keep the NativeArray around after passing it to CombineDependencies(nativeArray)? Can I call Dispose() on the array right after combining all the job handles into a single one?

I mean, will this explode in some way?:

NativeArray<JobHandle> deps = new NativeArray<JobHandle>(5 ,Allocator.TempJob, NativeArrayOptions.UninitializedMemory);
// fill the array with handles here
JobHandle combined = JobHandle.CombineDependencies(deps);
deps.Dispose();
// use combined JobHandle here

You can dispose the array after the call, it’s safe.

Why make it Allocator.TempJob then? Is it safe to use Allocator.Temp given its lifespan?

Both are safe options. You can use Allocator.Temp as well.
