Description
This diagram depicts what happens when
an item (B2) is deleted.
Notice that the reference item (B2) is
removed immediatly. This causes the reference counter in (A4) to be reduced.
A delete flag is set in (A4) because there are still references to it and
deletion is delayed until all references are removed. (C) and (C1) are
oblivious to the delete.
Navigation is affected by (A4) being flagged
for delete. Navigation functions such as; lstFirst and lstNext will skip
(hide) any items which are flagged for delete. This prevents deleted items
from getting more references.
