Description

TCache implements a cache class: it is a list-like class, but which uses a counting mechanism, and keeps a Most-Recent-Used list; this list represents the 'cache'. The list is internally kept as a doubly-linked list.

The Data property offers indexed access to the array of items. When accessing the array through this property, the MRUSlot property is updated.
