Alarm Message Service: Collection Interfaces
Table of Contents
Introduction
As we are dealing with abstract factories here, the implementation is not yet important in the first step. We define the interfaces for the collections so that we can define the interfaces for factories. This will be the basis for a factory provider so that the software becomes independent of concrete implementations because that is what it is essentially about.

In this example, we use just the easy-to-understand insertion sort algorithm, but it has a poor 0(n²), so we should provide the possibility to inject an efficient sort algorithm. For example, the linked-list-merge-sort from here: https://ekv-app-git-p01.ekvip.de/CNMTC3/cnm-collections-lib.
