Glossary
abstraction A model of a real-world object or concept abstract class A class that has no instances It is usually defined with the assumption that concrete subclasses will be derived from it, and extend its basic attributes and behavior In Java, an abstract class is one that includes an abstract method accessor A method that can access the state of an object actor An actor is an object that can operate on other objects, but is never operated on by other objects itself agent An agent can both operate on other objects and provide services to other objects As the name implies, it often serves as an agent or intermediary between other objects aggregation A whole/part hierarchy An aggregate object includes (has-a) other objects, each of which is considered to be a part of (part-of) the aggregate object API Application Programming Interface The specification of how a programmer writing an application accesses the behavior and state of classes and objects application server A server program that allows the installation of application specific software components, in a manner so that they can be remotely invoked, usually by some form of remote object method call
