TFPGInterfacedObjectList class

In unit fgl

Generic interfaced object list.

Declaration

pascal

TFPGInterfacedObjectList<T> = class(TFPSList)

Inheritance

TFPGInterfacedObjectList
TFPSList
TObject

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 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.
