Values
| 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 used as the default template for all instances of a class. One object is created for each class. |
| RF_ArchetypeObject | This object can be used as a template for instancing objects. This is set on all types of object templates. |
| 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 subobject templates that were created in a class constructor, and all instances created from those templates. |
| 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 | Flagged on subobject templates stored inside a class instead of the class default object, they are instanced after default subobjects. |
| 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_WillBeLoaded | RF_Dynamic =0x04000000, ///< Was removed along with bp nativization. |
| RF_HasExternalPackage | This object has an external package assigned and should look it up when getting the outermost package. |
| RF_HasPlaceholderType | This object was instanced from a placeholder type (e.g. on load). References to it are serialized but externally resolve to NULL from a logical point of view (for type safety). |
| RF_MirroredGarbage | Garbage from logical point of view and should not be referenced. This flag is mirrored in EInternalObjectFlags as Garbage for performance. |
| RF_AllocatedInSharedPage | Allocated from a ref-counted page shared with other UObjects. |
Remarks
Flags describing an object instance When modifying this enum, update the LexToString implementation!
