TSortedCollection.KeyOf function
Return the key of an item.
Declaration
function KeyOf(Item: Pointer): Pointer; virtualDescription
KeyOf returns the key associated with
Item.
TSortedCollection returns the item itself as the key, descendent
objects can override this method to calculate a (unique) key based on the
item passed (such as hash values).
Keys are used to sort the objects, they are used to search and sort
the items in the collection. If descendent types override this method then
it allows possibly for faster search/sort methods based on keys rather than
on the objects themselves.
Errors
None.
