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
| Type | Name | Description | |
|---|---|---|---|
 |
FGCObject () |
Tells the global object that forwards AddReferencedObjects calls on to objects that a new object is requiring AddReferencedObjects call. | |

Functions
| Type | Name | Description | |
|---|---|---|---|
 |
void | AddReferencedObjects
(
FReferenceCollector& Collector |
Pure virtual that must be overloaded by the inheriting class. |
  |
FString | Overload this method to report a name for your referencer | |
   |
bool | GetReferencerPropertyName
(
UObject* Object, |
Overload this method to report how the specified object is referenced, if necessary |
 |
void | Register with GC, only needed if constructed with EFlags::RegisterLater or after unregistering | |
  |
void | StaticInit () |
Initializes the global object referencer and adds it to the root set. |
 |
void | Unregister ahead of destruction. Safe to call multiple times. |
