 ====== Detail ======
-Details are the main building data blocks in Apparatus. They are high-level entities (unlike Traits), which support some additional ECS+ functionality like multi-iterating and inheritance.

+Details do derive from [[ue>API/Runtime/CoreUObject/UObject/UObject|UObject]] and are subject to garbage collecting and Unreal's general memory model (unlike Traits which use their own memory organization).
+If you need to change some of the Detail members, you can do it *directly* via members' assignment or calling non-const Detail's methods. No need to re-apply or copy the Detail data again.
+As an optimization of some internal logic, Details can't really be removed from Subjectives. They can only be *disabled*. This is effectively the same thing as removal since [[en:toolworks:docs:apparatus:filter|Filters]] do respect this enabled/disabled state both in including and excluding contexts.
