UCLASS (MinimalAPI, Abstract)  
class UMetaDataRegistrySource : public UDataRegistrySource

Name	Type	Remarks	Include Path
FRegisteredAsset	TPair< FAssetData, int32 >	List of specific assets registered with source, in runtime order sorted by priority	DataRegistrySource.h

Name	Type	Remarks	Include Path	Unreal Specifiers
AssetUsage	EMetaDataRegistrySourceAssetUsage	Asset usage	DataRegistrySource.h	EditAnywhere Category=DataRegistry

Name	Remarks	Include Path
virtual void DetermineRuntimeNames ( TArray< FName >& OutRuntimeNames )	Fills in list of desired runtime names, must be overridden!	DataRegistrySource.h
virtual bool DoesAssetPassFilter ( const FAssetData& AssetData, bool bNewRegisteredAsset )	Returns true if this asset data passes the filter for this meta source, bNewRegisteredAsset is true if it comes from a RegisterSpecificAsset call and needs extra path checking	DataRegistrySource.h
virtual TSubclassOf< UDataRegistrySource > GetChildSourceClass()	Returns what subclass of source to use for children, must be overridden!	DataRegistrySource.h
virtual bool SetDataForChild ( FName SourceName, UDataRegistrySource* ChildSource )	Fills in new or existing child source for specific name, must be overridden!	DataRegistrySource.h

Name	Remarks	Include Path
virtual void AddRuntimeSources ( TArray< UDataRegistrySource* >& OutRuntimeSources )	Gets the list of runtime sources that should be registered for this source, will either be itself or a list of children	DataRegistrySource.h
virtual bool IsSpecificAssetRegistered ( const FSoftObjectPath& AssetPath ) const	Returns true if this asset is already registered with this source	DataRegistrySource.h
virtual void RefreshRuntimeSources()	Called to regenerate runtime sources if needed, won't do anything for simple sources	DataRegistrySource.h
virtual EDataRegistryRegisterAssetResult RegisterSpecificAsset ( const FAssetData& AssetData, int32 AssetPriority )	Attempt to register a specified asset with a source, returns an EDataRegistryRegisterAssetResult, indicating whether the asset was registered or not.	DataRegistrySource.h
virtual int32 UnregisterAssetsWithPriority ( int32 AssetPriority )	Unregisters all previously registered assets in a specific registry with a specific priority, can be used as a batch reset.	DataRegistrySource.h
virtual bool UnregisterSpecificAsset ( const FSoftObjectPath& AssetPath )	Removes references to a specific asset, returns bool if it was removed	DataRegistrySource.h

Name	Remarks	Include Path	Unreal Specifiers
virtual void OnNewAssetSearchRoot ( const FString& SearchRoot )	Callback registered when an asset search root as been added post launch	DataRegistrySource.h
virtual void SortRegisteredAssets()	Sort assets, default order is by priority then array order	DataRegistrySource.h
