Class TypeManager.TypeOverridesAttribute
[TypeOverrides] can be applied to a component that is known to never contain Entity and/or Blob references, in order to reduce time taken during serialization operations.
Namespace: Unity.Entities
Syntax
[AttributeUsage(AttributeTargets.Class | AttributeTargets.Struct)]
public class TypeOverridesAttribute : Attribute, _AttributeRemarks
For example, a managed component containing a base class type field can only be determined to have entity or blob references at runtime since the runtime instance might hold a child type instance which does contain Entity and/or BlobAssetReferences. As such, serializing operations for managed components needs to walk runtime type instances which might be unnecessary. Use this attribute to prevent this walking to improve managed component serialization operations when you know the component type will never contain Entity and/or Blob references.
