Values

Name

Description

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_Parsed

Successfully parsed.

CLASS_MatchedSerializers

CLASS_AdvancedDisplay

All the properties on the class are shown in the advanced section (which is hidden by default) unless SimpleDisplay is specified on the property

CLASS_Native

Class is a native class - native interfaces will have CLASS_Native set, but not RF_MarkAsNative

CLASS_NoExport

Don't export to C++ header.

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_CustomConstructor

Do not export a constructor for this class, assuming it is in the cpptext

CLASS_Const

All properties and functions in this class are const and should be exported as const

CLASS_LayoutChanging

Class flag indicating the class is having its layout changed, and therefore is not ready for a CDO to be created

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 /..../Blah.ini (as opposed to CLASS_DefaultConfig)

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.

Remarks
