Values
| Name | Remarks |
|---|---|
| CLASS_None | No Flags |
| CLASS_Abstract | Class is abstract and can't be instantiated directly. |
| CLASS_DefaultConfig | Save object configuration only to Default INIs, never to local INIs. |
| CLASS_Config | Load object configuration at construction time. |
| CLASS_Transient | This object type can't be saved; null it out at save time. |
| CLASS_Optional | This object type may not be available in certain context. |
| CLASS_MatchedSerializers | |
| CLASS_ProjectUserConfig | Indicates that the config settings for this class will be saved to Project/User*.ini (similar to CLASS_GlobalUserConfig) |
| CLASS_Native | Class is a native class - native interfaces will have CLASS_Native set, but not RF_MarkAsNative |
| CLASS_NotPlaceable | Do not allow users to create in the editor. |
| CLASS_PerObjectConfig | Handle object configuration on a per-object basis, rather than per-class. |
| CLASS_ReplicationDataIsSetUp | Whether SetUpRuntimeReplicationData still needs to be called for this class |
| CLASS_EditInlineNew | Class can be constructed from editinline New button. |
| CLASS_CollapseCategories | Display properties in the editor without using categories. |
| CLASS_Interface | Class is an interface |
| CLASS_PerPlatformConfig | Config for this class is overridden in platform inis, reload when previewing platforms |
| CLASS_Const | All properties and functions in this class are const and should be exported as const |
| CLASS_NeedsDeferredDependencyLoading | Class flag indicating objects of this class need deferred dependency loading |
| CLASS_CompiledFromBlueprint | Indicates that the class was created from blueprint source material |
| CLASS_MinimalAPI | Indicates that only the bare minimum bits of this class should be DLL exported/imported |
| CLASS_RequiredAPI | Indicates this class must be DLL exported/imported (along with all of it's members) |
| CLASS_DefaultToInstanced | Indicates that references to this class default to instanced. |
| CLASS_TokenStreamAssembled | Indicates that the parent token stream has been merged with ours. |
| CLASS_HasInstancedReference | Class has component properties. |
| CLASS_Hidden | Don't show this class in the editor class browser or edit inline new menus. |
| CLASS_Deprecated | Don't save objects of this class when serializing |
| CLASS_HideDropDown | Class not shown in editor drop down for class selection |
| CLASS_GlobalUserConfig | Class settings are saved to |
| CLASS_Intrinsic | Class was declared directly in C++ and has no boilerplate generated by UnrealHeaderTool |
| CLASS_Constructed | Class has already been constructed (maybe in a previous DLL version before hot-reload). |
| CLASS_ConfigDoNotCheckDefaults | Indicates that object configuration will not check against ini base/defaults when serialized |
| CLASS_NewerVersionExists | Class has been consigned to oblivion as part of a blueprint recompile, and a newer version currently exists. |
