Base class of all classes. |
TFPGList can be used to specialize a list for any class type T that requires reference counting (all objects that implement IInterface or IUnknown)). It will specialize to a list with the same methods as TFPSList or classes.TFPList or TFPObjectList
Classes that implement IInterface or IUnknown require special care to maintain the reference count. The TFPGInterfacedObjectList list provides the necessary functionality to deal with this.
