##Introduction

This program utilises the Reflection API, to calculate the Positional Stability(1) of each class contained with in a Jar file. The stability metric is calculated by finding both the Efferent(ce) and Afferent(ca) couplings of each class and then performing the following calculation, 1 = ce/ce + ca. To find the dependencies and different couplings of each class, we used the Reflection API. The application was built using the MVC design pattern. The application uses the Swing library to create GUI's, which the user interacts with.

##Deploying the Application

To run this program, you need Java 8 installed.
Open command prompt, navigate to OOReflectionGUIProject
Example of how to run the program

java -cp ./bin:./lib/test-jar.jar ie.gmit.sw.GUIView.Runner ./lib/test-jar.jar

##Design Pattern and Features

####MVC The program follows the MVC pattern. As we are using a GUI for the application, the MVC pattern works quiet well. The project structure is as follows

OOProjectGui
│       
│
└───Controller
    |--CalculateCouplings
    |--ClassList
    |--ClassMap
    |--Data
    |--DatabaseConnector
    |--PopulateAdjacency
    |--Readable
    |--ReadinJarFile
└───GUIView
    │--AdjacencySummary
    │--AdjacencySummaryTable
    |--AppSummary
    |--AppWindow
    |--CustomControl
    |--Runner
    |--TypeSummaryTableModel
└───Model
    |--AdjacencyList
    |--Measurement

####Strategy In Strategy pattern, a class behaviour or its algorithm can be changed at run time. By using this pattern, we could easily create classes which would implement the Readable interface and could import different file types e.g. zip.

public interface Readable {
    ClassList init(String var1) throws IOException, NoSuchMethodException;
}

####Adjacency List The program creates an Adjacency List for each class and is represented in the GUI. The list is stored in the AdjacencyList class which has a HashMap as a parameter
