List with extended functionality: slices of ViewList objects are child lists, linked to their parents. Changes made to a child list also affect the parent list. A child list is effectively a "view" (in the SQL sense) of the parent list. Changes to parent lists, however, do not affect active child lists. If a parent list is changed, any active child lists should be recreated.
The start and end of the slice can be trimmed using the trim_start()
and
trim_end()
methods, without affecting the parent list. The link between
child and parent lists can be broken by calling disconnect()
on the
child list.
Also, ViewList objects keep track of the source & offset of each item.
This information is accessible via the source()
, offset()
, and
info()
methods.
