Variables

	Name	Description
bool	bAllowResaveAtTheEndIfRequested	TRUE if this reinstancer should resave compiled Blueprints if the user has requested it
bool	bHasReinstanced	Whether or not this resinstancer has already reinstanced
bool	bIsRootReinstancer	TRUE if this is the root reinstancer that all other active reinstancing is spawned from
bool	bUseDeltaSerializationToCopyProperties	TRUE if delta serialization should be forced during FBlueprintCompileReinstancer::CopyPropertiesForUnrelatedObjects
TArray< UBluepr...	Children	Children of this blueprint, which will need to be recompiled and relinked temporarily to maintain the class layout
UClass *	ClassToReinstance	Reference to the class we're actively reinstancing
uint32	ClassToReinstanceDefaultValuesCRC
UClass *	DuplicatedClass	Reference to the duplicate of ClassToReinstance, which all previous instances are now instances of
TMap< FName, UF...	FunctionMap
TSet< UObject &...	ObjectsThatShouldUseOldStuff	Objects that should keep reference to old class
UObject *	OriginalCDO	The original CDO object for the class being actively reinstanced
TMap< FName, FP...	PropertyMap	Mappings from old fields before recompilation to their new equivalents
EReinstClassTyp...	ReinstClassType

Constructors

	Name	Description
	FBlueprintCompileReinstancer()	Default constructor, can only be used by derived classes
	FBlueprintCompileReinstancer ( UClass* InClassToReinstance, EBlueprintCompileReinstancerFlags F... )	Sets the reinstancer up to work on every object of the specified class

Destructors

	Name	Description
	~FBlueprintCompileReinstancer()

Functions

	Name	Description
void	BatchReplaceInstancesOfClass ( TMap< UClass, UClass > ..., const FBatchReplaceInstancesOfClass... )	Batch replaces a mapping of one or more classes to their new class by leveraging ReplaceInstancesOfClass
void	BlueprintWasRecompiled ( UBlueprint* BP, bool bBytecodeOnly )
void	CompileChildren()
void	CopyPropertiesForUnrelatedObjects ( UObject* OldObject, UObject* NewObject, bool bClearExternalReferences, bool bForceDeltaSerialization )	Attempts to copy as many properties as possible from the old object to the new.
TSharedPtr< ...	Create ( UClass* InClassToReinstance, EBlueprintCompileReinstancerFlags F... )
void	FinalizeFastReinstancing ( TArray< UObject* >& ObjectsTo... )
void	GenerateFieldMappings ( TMap< FFieldVariant, FFieldVariant ... )	Helper to gather mappings from the old class's fields to the new class's version
void	GetSortedClassHierarchy ( UClass* ClassToSearch, TArray< UClass* >& OutHierarc..., UClass** OutNativeParent )	Gathers the full class Hierarchy of the ClassToSearch, sorted top down (0 index being UObject, n being the subclasses)
bool	IsClassObjectReplaced()
bool	IsReinstancingSkeleton()
bool	IsReinstClass ( const UClass* Class )	Returns true if the given class is a REINST class (starts with the 'REINST_' prefix)
void	ListDependentBlueprintsToRefresh ( const TArray< UBlueprint* >& ... )
UClass *	MoveCDOToNewClass ( UClass* OwnerClass, const TMap< UClass*, UClass&#..., bool bAvoidCDODuplication )	Function used to safely discard a CDO, so that the class can have its layout changed, callers must move parent CDOs aside before moving child CDOs aside:
void	MoveDependentSkelToReinst ( UClass* OwnerClass, TMap< UClass, UClass > ... )	Moves CDOs aside to immutable versions of classes(`REINST_) so that the CDO's can safely be GC'd.
void	OptionallyRefreshNodes ( UBlueprint* BP )
void	ReconstructOwnerInstances ( TSubclassOf< UActorComponent > Comp... )	When re-instancing a component, we have to make sure all instance owners' construction scripts are re-ran (in-case modifying the component alters the construction of the actor).
TSharedPtr< ...	ReinstanceFast()
TSharedPtr< ...	ReinstanceInner ( bool bForceAlwaysReinstance )
void	ReinstanceObjects ( bool bForceAlwaysReinstance )	Reinstances all objects in the ObjectReinstancingMap
void	ReparentChild ( UBlueprint* ChildBP )	Reparents the specified blueprint or class to be the duplicated class in order to allow properties to be copied from the previous CDO to the new one
void	ReparentChild ( UClass* ChildClass )	Reparents the specified blueprint or class to be the duplicated class in order to allow properties to be copied from the previous CDO to the new one
void	ReplaceInstancesOfClass ( UClass* OldClass, UClass* NewClass, UObject* OriginalCDO, TSet< UObject* >* Objects..., bool bClassObjectReplaced, bool bPreserveRootComponent )	Worker function to replace all instances of OldClass with a new instance of NewClass
void	ReplaceInstancesOfClassEx ( const FReplaceInstancesOfClassParam... )	Worker function to replace all instances of OldClass with a new instance of NewClass
void	SaveClassFieldMapping ( UClass* InClassToReinstance )	Saves a mapping of field names to their UField equivalents, so we can remap any bytecode that references them later
bool	ShouldPreserveRootComponentOfReinstancedActor()	Determine whether reinstancing actors should preserve the root component of the new actor
void	UpdateBytecodeReferences()	Updates references to properties and functions of the class that has in the bytecode of dependent blueprints
void	VerifyReplacement()	Verify that all instances of the duplicated class have been replaced and collected

Overridden from FGCObject

		Name	Description
	void	AddReferencedObjects ( FReferenceCollector& Collector )	Pure virtual that must be overloaded by the inheriting class.
	FString	GetReferencerName()	Use this method to report a name for your referencer.

Enums

	Name	Description
	EReinstClassType	Cached value, mostly used to determine if we're explicitly targeting the skeleton class or not

Deprecated Functions

		Name	Description
	void	EnlistDependentBlueprintToRecompile ( UBlueprint* BP, bool bBytecodeOnly )	This method performs no function and isn't invoked by the base class. Remove all calls to the base class method.
