Module Name:
|
||
|
|
|
||
|
|
seqcnt.hxx
|
||
|
|
|
||
|
|
Abstract:
|
||
|
|
|
||
|
|
This module contains the declaration for the SEQUENTIAL_CONTAINER class.
|
||
|
|
SEQUENTIAL_CONTAINER is a fairly primitive class which augments the
|
||
|
|
CONTAINER class by adding the capability that the objects stored in the
|
||
|
|
container have some sort of sequenced relationship. This means that
|
||
|
|
OBJECTs can be queried from SEQUENTIAL_CONTAINERs by the use of an
|
||
|
|
ITERATOR and that the concepts first, last, next and previous have
|
||
|
|
meaning.
