 |
FDelegateHandle | NewAssetSearchRootHandle | Delegate handle for OnNewAssetSearchRoot |
   |
TMap< FName, TObjectPtr< UDataRegistrySource > > | RuntimeChildren | Map from source identifier such as package name to registered child |

Functions
| Type | Name | Description | |
|---|---|---|---|
  |
void | DetermineRuntimeNames
(
TArray< FName >& OutRuntimeNames |
Fills in list of desired runtime names, must be overridden! |
  |
bool | DoesAssetPassFilter
(
const FAssetData& AssetData, |
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 |
   |
TSubclassOf< UDataRegistrySource > | Returns what subclass of source to use for children, must be overridden! | |
  |
void | OnNewAssetSearchRoot
(
const FString& SearchRoot |
Callback registered when an asset search root as been added post launch |
  |
bool | SetDataForChild
(
FName SourceName, |
Fills in new or existing child source for specific name, must be overridden! |
  |
void | Sort assets, default order is by priority then array order |
Overridden from UDataRegistrySource
| Type | Name | Description | |
|---|---|---|---|
  |
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 |
   |
bool | IsSpecificAssetRegistered
(
const FSoftObjectPath& AssetPath |
Returns true if this asset is already registered with this source |
  |
void | Called to regenerate runtime sources if needed, won't do anything for simple sources | |
  |
bool | RegisterSpecificAsset
(
const FAssetData& AssetData, |
Attempt to register a specified asset with a source, returns true if any changes were made. |
  |
int32 | UnregisterAssetsWithPriority
(
int32 AssetPriority |
Unregisters all previously registered assets in a specific registry with a specific priority, can be used as a batch reset. |
  |
bool | UnregisterSpecificAsset
(
const FSoftObjectPath& AssetPath |
Removes references to a specific asset, returns bool if it was removed |
Typedefs
| Name | Description |
|---|---|
| FRegisteredAsset | List of specific assets registered with source, in runtime order sorted by priority |
