Detailed Description

Intrusive Many to Many Relationship.

This file defines a trio of templates (ManyManyLinkRoot, ManyManyLinkLink, and ManyManyLinkNode) that implement a many-to-many interconnect web.

Warning: The ManyMany classes are new, and have not been extensively tested

Bug: The Locking implemented in the ManyMany containers is likely not sufficient yet.

Overview

ListInRoot and ListInNode provide a simple API to allow classes to provide a basic List <-> Node relationship (1 List holding many Nodes), with a singly linked list. (c.f. DListin.h, DListInRoot, and DListInNode for doubly linked list)

To create this relationship, the class to act as the list derives from the template ListInRoot, and the class to act as the Node from ListInNode, both with a first parameter of the class name of the List class, and a second parameter of the Node class. There is an optional integral 3rd parameter to allow the classes to inherent from these multiple times if you need to represent multiple simultaneous relationships. This inheritance should be public, or you need to add the ListInRoot and ListInNode templates as friends.

At the point of declaration, both classes need to be declared, so you will typically have a forward of the other class before the definition of the class. At the point of usage of members, generally the full definition of both classes is needed to instance the code for the template.

Inside this file, the following types have the following meanings:

R: The "user" type that will be derived from ListInRoot

N: The "user" type that will be derived from ListInNode

n: The integer parameter for the template to allow multiple usage

Root: The particular instance of ListInRoot<R, N, n> being used

Node: The particular instance of ListInNode<R, N, n> being used

node: will have type N*, to be used when walking the list.
