TInheritedGuardValueAccessors | Unreal Engine 5.8 Documentation

API > API/Runtime > API/Runtime/Core

Combines TGuardValueAccessors with FInheritedContextExtension + FInheritedContextExtensionScope. Like TInheritedGuardValue but for variables accessed through getter/setter functions rather than direct references. Getter and Setter are compile-time function pointers baked into the extension callbacks — no TFunction overhead.

Usage (creates extension internally): TInheritedGuardValueAccessors<&UE::IsSavingPackage, &UE::SetIsSavingPackage> Guard(true);

Usage with pre-built extension (avoids allocation per guard): static auto GExt = UE::MakeInheritedContextExtension<&UE::IsSavingPackage, &UE::SetIsSavingPackage>(); TInheritedGuardValueAccessors<&UE::IsSavingPackage, &UE::SetIsSavingPackage> Guard(GExt, true);
