Name

Description

RF_NoFlags

No flags, used to avoid a cast.

RF_Public

Object is visible outside its package.

RF_Standalone

Keep object around for editing even if unreferenced.

RF_MarkAsNative

Object (UField ) will be marked as native on construction (DO NOT USE THIS FLAG in HasAnyFlags() etc)

RF_Transactional

Object is transactional.

RF_ClassDefaultObject

This object is its class's default object.

RF_ArchetypeObject

This object is a template for another object - treat like a class default object.

RF_Transient

Don't save object.

RF_MarkAsRootSet

This group of flags is primarily concerned with garbage collection.

RF_TagGarbageTemp

This is a temp user flag for various utilities that need to use the garbage collector. The garbage collector itself does not interpret it.

RF_NeedInitialization

The group of flags tracks the stages of the lifetime of a uobject.

RF_NeedLoad

During load, indicates object needs loading.

RF_KeepForCooker

Keep this object during garbage collection because it's still being used by the cooker.

RF_NeedPostLoad

Object needs to be postloaded.

RF_NeedPostLoadSubobjects

During load, indicates that the object still needs to instance subobjects and fixup serialized component references.

RF_NewerVersionExists

Object has been consigned to oblivion due to its owner package being reloaded, and a newer version currently exists.

RF_BeginDestroyed

BeginDestroy has been called on the object.

RF_FinishDestroyed

FinishDestroy has been called on the object.

RF_BeingRegenerated

Misc. Flags.

RF_DefaultSubObject

Flagged on subobjects that are defaults.

RF_WasLoaded

Flagged on UObjects that were loaded.

RF_TextExportTransient

Do not export object to text form (e.g. copy/paste). Generally used for sub-objects that can be regenerated from data in their parent object.

RF_LoadCompleted

Object has been completely serialized by linkerload at least once. DO NOT USE THIS FLAG, It should be replaced with RF_WasLoaded.

RF_InheritableComponentTemplate

Archetype of the object can be in its super class.

RF_DuplicateTransient

Object should not be included in any type of duplication (copy/paste, binary duplication, etc.)

RF_StrongRefOnFrame

References to this object from persistent function frame are handled as strong ones.

RF_NonPIEDuplicateTransient

Object should not be included for duplication unless it's being duplicated for a PIE session.

RF_Dynamic

RF_WillBeLoaded

Field Only. Dynamic field - doesn't get constructed during static initialization, can be constructed multiple times.

Remarks

Flags describing an object instance
