CS 5010 Module 10

Module Overview

In this module, we will learn how to make objects communicate with each other and that there are two basic models for communication: pull and push. We will also learn that objects must have identity in order to communicate reliably, and how to use state to implement objects with stable identities.

In addition, we will discuss how and when to use the publish-subscribe pattern to implement push-style communication between unrelated objects.
