Syntax

class FGCObject

Remarks

This class provides common registration for garbage collection for non-UObject classes. It is an abstract base class requiring you to implement the AddReferencedObjects() method.

Constructors

	Name	Description
	FGCObject()	Tells the global object that forwards AddReferencedObjects calls on to objects that a new object is requiring AddReferencedObjects call.
	FGCObject ( FGCObject const& )	Copy constructor
	FGCObject ( FGCObject&& )	Move constructor

Destructors

	Name	Description
	~FGCObject()	Removes this instance from the global referencer's list

Functions

	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.
bool	GetReferencerPropertyName ( UObject* Object, FString& OutPropertyName )	Use this method to report how the specified object is referenced, if necessary
void	StaticInit()	Initializes the global object referencer and adds it to the root set.

Constants

Name	Description
GGCObjectReferencer	The static object referencer object that is shared across all garbage collectible non-UObject objects.
UnknownGCObjectName	Default name for unnamed FGCObjects
