Inheritance¶

Description¶

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.

Properties¶

Member	Visibility	Description
First	public	First non-nil object.
Items	public	Indexed access to objects in the list.
