ComponentGroup - GetComponentArray

I've got a question about the API on the ComponentGroup struct.. there doesn't appear to be any GetComponentArray method (components attached to a GameObject), but there are methods for IComponentData and ISharedComponentData.

Is there a technical reason that this wasn't included?

 

I don't know what component group you are looking for...

But there are all methods to get ComponentArrays, ComponentDataArrays and so on!

Metadata of ComponentGroup:

Code (CSharp):

1.     public class ComponentGroup : IDisposable {
2.         public ComponentType[] Types { get; }
3.         public bool IsEmptyIgnoreFilter { get; }
4.  
5.         public void AddDependency(JobHandle job);
6.         public int CalculateLength();
7.         public bool CompareComponents(ComponentType[] componentTypes);
8.         public void CompleteDependency();
9.         public ForEachComponentGroupFilter CreateForEachFilter<SharedComponent1>(List<SharedComponent1> sharedComponent1) where SharedComponent1 : struct, ISharedComponentData;
10.         public void Dispose();
11.         public int GetCombinedComponentOrderVersion();
12.         public ComponentDataArray<T> GetComponentDataArray<T>(ForEachComponentGroupFilter filter, int filterIdx) where T : struct, IComponentData;
13.         public ComponentDataArray<T> GetComponentDataArray<T>() where T : struct, IComponentData;
14.         public JobHandle GetDependency();
15.         public EntityArray GetEntityArray();
16.         public FixedArrayArray<T> GetFixedArrayArray<T>() where T : struct;
17.         public SharedComponentDataArray<T> GetSharedComponentDataArray<T>() where T : struct, ISharedComponentData;
18.         public void ResetFilter();
19.         public void SetFilter<SharedComponent1>(SharedComponent1 sharedComponent1) where SharedComponent1 : struct, ISharedComponentData;
20.     }
21. }

MetaData of ComponentGroupExtensionsForComponentArray

Code (CSharp):

1.    public static class ComponentGroupExtensionsForComponentArray {
2.         public static ComponentArray<T> GetComponentArray<T>(this ComponentGroup group) where T : Component;
3.     }

 

Those pesky extension functions! Thanks
