Inheritance¶

Description¶

TFPSList can be seen as the generalized equivalent of the classes unit TFPList list. It is used as a base class for the TFPGList, TFPGMap, TFPGObjectList, TFPGInterfacedObjectList and TFPGMapInterfacedObjectData generic classes.

This list is not meant to be used directly, it is an auxiliary class for the actual generic list classes.

Properties¶

Items	public	Items in the list.
ItemSize read only	public	Size of the items in the list.
Last	public	Pointer to last non-empty item in the list.
