Typedef Documentation

FAssetDataMap

using UE::AssetRegistry::Private::FAssetDataMap = typedef TSet<FAssetData*, FCachedAssetKeyFuncs>

When not using indirection, an FAssetDataMap is a TSet, but with the complication that it stores pointers to FAssetData while supporting lookup by FCachedAssetKey.

See also

FCachedAssetKey.

FConstAssetDataMap

using UE::AssetRegistry::Private::FConstAssetDataMap = typedef TSet<const FAssetData*, FCachedAssetKeyFuncs>

FInterfaceRWLock

using UE::AssetRegistry::Private::FInterfaceRWLock = typedef FRWLockWithPriority

		int32	TotalMatches
	)

AssetDataMatchesTag()

bool UE::AssetRegistry::Private::AssetDataMatchesTag	(	const FAssetData *	AssetData,
		FName	TagName,

ConcatenateOuterPathAndObjectName()

COREUOBJECT_API void UE::AssetRegistry::Private::ConcatenateOuterPathAndObjectName	(	FStringBuilderBase &	Builder,
		FName	OuterPath,

	)

Concatenates an existing object path with an inner object with the correct separator ('.' or ':'). Assumes the outer path already contains correct separators.
