TIntList is an integer list that works like TStringList except with integers instead of strings. None of the integer list classes I have seen include the associated object list like TStringList does. TIntList includes this. You can also save and load from files and streams, or optionally save and load to and from text files and streams.

TObjIntList descends from TIntList. It overrides several methods to automatically create and free the objects in the associated list. The user of this object simply needs to write and assign a function (OnAutoCreateObject) that creates the object. There is also an OnAutoFreeObject event that can contain anything that you may need to do before freeing an associated object. TObjIntList will then always contain an associated object with an integer, and free it when the integer is removed from the list. This saves you from remembering to create and free the objects yourself.
