Values
| Name | Remarks |
|---|---|
| None | |
| ReachabilityFlag0 | One of the flags used by Garbage Collector to determine UObject's reachability state. |
| ReachabilityFlag1 | One of the flags used by Garbage Collector to determine UObject's reachability state. |
| ReachabilityFlag2 | One of the flags used by Garbage Collector to determine UObject's reachability state. |
| AutoRTFMConstructionAborted | |
| Remote | |
| RemoteReference | |
| LoaderImport | Object is ready to be imported by another package during loading. |
| Garbage | Garbage from logical point of view and should not be referenced. This flag is mirrored in EObjectFlags as RF_Garbage for performance. |
| AsyncLoadingPhase1 | Object is being asynchronously loaded. |
| ReachableInCluster | External reference to object in cluster exists. |
| ClusterRoot | Root of a cluster. |
| Native | Native (UClass only). |
| Async | Object exists only on a different thread than the game thread. |
| AsyncLoadingPhase2 | Object is being asynchronously loaded. |
| Unreachable | Object is not reachable on the object graph. |
| RefCounted | Object currently has ref-counts associated with it. |
| RootSet | Object will not be garbage collected, even if unreferenced. |
| PendingConstruction | Object didn't have its class constructor called yet (only the UObjectBase one to initialize its most basic members) |
