Package ikr.simlib.model Description

Model Components

A major advantage of the IKR Simulation Library is the easy construction of a model from model components (e.g. queues, service units) that are then connected together with the help of the port concept.

General Classes

Hierarchical Models: Class SimNode

The IKR SimLib supports the building of hierarchical models. Therefore, there is an interface to build a model hierarchy, which is called SimNode. The top node of the hierarchy belongs to an object of the class Model. All other nodes of the hierarchy can belong to objects of arbitrary type.
There is a default implementation of a SimNode called StdSimNode, which already implements the methods listed in SimNode.

Every simulation program has one single instance of the class SimNodeManager. This object knows the root of the model hierarchy and can traverse the hierarchy for purpose of printing.

Model Component Base Class: Class Entity

Model components can be derived from the class Entity.
Within the simulation library, several model components already exist which have been derived from Entity. These classes will be introduced in the following.

Complete Model: Class Model

At the top of the hierarchically ordered model components, there is a model component derived from Model.

Port Concept

Model components communicate with each other using messages / cells / packets via so-called ports. Therefore, the model components have a defined interface which increases their re-usability.
