UAssetManager::IsAssetDataBlueprintOfClassSet

function Engine Since 4.22

#include "Engine/AssetManager.h"

Access: public Specifiers: virtualconst

Description

Checks whether the given asset data is a Blueprint whose base class appears in ClassNameSet. This reads the parent class asset registry tag rather than loading the asset.

Caveats & Gotchas

• Relies on the ParentClass tag written into the asset registry, so it only works for assets that have already been scanned and tagged correctly (older cooked content or manually-added assets can be missing this tag).
• Does not walk the full inheritance chain beyond what the tag records — it checks the immediate parent class recorded for the Blueprint, not every ancestor.
• Used internally during directory scanning to classify Blueprint assets without forcing a full load of each one, which keeps startup scans fast.

Signature

virtual bool IsAssetDataBlueprintOfClassSet(const FAssetData& AssetData, const TSet<FTopLevelAssetPath>& ClassNameSet) const

Parameters

Name	Type	Description	Default
AssetData	const FAssetData&	Asset registry entry to test.	—
ClassNameSet	const TSet<FTopLevelAssetPath>&	Set of class paths to check the Blueprint's parent class against.	—

bool

Example

Filter Blueprint assets by parent class C++

TSet<FTopLevelAssetPath> AllowedParents;
AllowedParents.Add(FTopLevelAssetPath(AItem::StaticClass()));

if (UAssetManager::Get().IsAssetDataBlueprintOfClassSet(AssetData, AllowedParents))
{
	// AssetData is a Blueprint derived from AItem
}
