Classes

  Type Name Description
Public class FDataValidationContext This class is used to interface between UObject::IsDataValid and the data validation system.  
Public struct FDependencyQuery A struct that is equivalent to EDependencyQuery, but is more useful for performance in filtering operations.  
Public class FEditorPathHelper Helper class that can build Editor FSoftObjectPath(s) based on EditorPathOwners in an object's outer chain.  
Public class FExclusiveLoadPackageTimeTracker A singleton to keep track of the exclusive load time of every package.  
Public class FFiltering    
Public class FNotifyHook Notification hook.  
Public class FPackageAccessRefScope    
Public class FPackageName    
Public class FPackagePath Internal class only; not used by blueprints.  
Public class FRedirectCollector    
Public struct FTrackedData    
Public struct FTransactionDiff Diff for a given transaction.  
Public struct FTransactionObjectChange Change information for an object that was transacted  
Public struct FTransactionObjectDeltaChange Delta-change information for an object that was transacted  
Public class FTransactionObjectEvent Transaction object events.  
Public struct FTransactionObjectId ID for an object that was transacted  
Public class FUObjectToken A Message Log token that links to an object, with default behavior to link to the object in the content browser/scene.  
Public class FWarnIfAssetsLoadedInScope    
Public class FWorldTileInfo Tile information used by WorldComposition.  
Public class FWorldTileLayer World layer information for tile tagging  
Public class FWorldTileLODInfo Describes LOD entry in a world tile  
Public class IAssetRegistryInterface Asset Registry module interface  
Public class IAssetRegistrySingleton Storage for the singleton IAssetRegistry* TODO: this storage should be a class static variable on IAssetRegistry, but that type is defined in the AssetRegistry module, and many modules try to access the singleton (and call virtual functions on it) without linking against the AssetRegistry module, so the storage for the singleton needs to be defined in a lower-level module that all of those modules do include  
Public class IEditorPathObjectInterface Interface to be implemented by Objects that can be part of an Editor Path through a Editor Path owner  
Public class ITransactionObjectAnnotation Interface for transaction object annotations.  
Public class UEditorPathObjectInterface    
Public class UTextBuffer Implements an object that buffers text.

Public enum EPackageExtension Enum for the extensions that a package payload can be stored under.  
Public enum EPackageSegment Enum for the different portions of a package than can be requested from a PackageResourceManager Not all segments are available in all PackageResourceManager; header is always available but the other segments are cooked-only  
Public enum ETransactionObjectChangeCreatedBy Different things that can create an object change  
Public enum ETransactionObjectEventType Different kinds of actions that can trigger a transaction object event

Functions

  Type Name Description
Public function EPackageSegment

ExtensionToSegment ( EPackageExtension PackageExtension
)

 Map a PackageExtension to a PackageSegment. All extensions can be used by only one segment
Public function void

FindPackageReferencesInObject ( const UObject* RootObject,
const TArray< FName >& PackagesReferenced,
TFunctionRef< void(FName, const FString&)> Callback
)

 Given a root object, this function will call the callback every time it encounters a reference in the root object (including all inlined/instanced UObjects. The returned references will be in an easily understood debugging format so that they're easy to understand the context.For example, Actions2->ObjectActivitiesInfo[0].TargetReferenceWhere TargetReference was one of the listed PackagesReferenced. The point of this function is to assist in the reporting of references between objects you need to show the developer.
Public function const TCHAR *

LexToString ( EPackageExtension PackageExtension
)

  
Public function const TCHAR *

LexToString ( EPackageSegment PackageSegment
)

  
Public function EPackageExtension

SegmentToExtension ( EPackageSegment PackageSegment
)

 Map a PackageSegment to a PackageExtension.

Public variable FRedirectCollector GRedirectCollector Global redirect collector callback structure
Public variable FName NAME_CookerBuildObject  
Public variable FName NAME_CreateDefaultObject  
Public variable FName NAME_Load  
Public variable FName NAME_NoAccessExpected A debug-only scope that is used to find global-scope operations.
Public variable FName NAME_PostLoad  
Public variable FName NAME_PreLoad  
Public variable FName NAME_ResetContext A global-scope operation suck as AssetRegistry tick is occurring on the current thread inside of another scope, and the references made during this operation should not be associated with the previous scope.
