TObject |
TLinkList is a class which defines a navigational interface for a simple doubly linked list.
TLinkList provides properties used to access the First and Last items in the linked list, the number of list items in Count, and the first free item in the linked list. Items in the linked list are represented using the TLinkListItem class, which provides Prior and Next properties for navigation of items in the list.
TLinkList contains an abstract virtual CreateItem method that is used to create new items for the linked list. The method must be implemented in a descendent class to provided implementation details that address storage and ownership of the linked list items. See TGtkMessageQueue for an example of a concrete implementation of the TLinkList class.
