| RootParentBookkeepingEntryList | Private::FUpdateEventBookkeepingList * | The root node doesn't have a parent but we need a bookkeeping list regardless. | TraitInterfaces/IUpdate.h | |
| UpdateStackHead | Private::FUpdateEntry * | The head pointer of the update stack This is the traversal execution stack and it contains entries that are pending their pre-update call and entries waiting for post-update to be called | TraitInterfaces/IUpdate.h |
