Class JarDependencies

java.lang.Object

org.jdepend.model.JarDependencies

public class JarDependencies
extends java.lang.Object

This class models a jar file or a class files directory. It can be used in several actions in the JDependency application. A JarDependencies contains:

• The list of paths found in this jar file or class files directory
• The list of dependencies

Usage

The simplest way to use this class is simply to create one JarDependencies and provide it a directory containing classes, or one jar file.

   JarDependencies depend = new JarDependencies(myJarFile);
 

It is then possible to use it in the application. One simple thing to do is checking if the JarDependencies has dependencies from another one. For example:

   JarDependencies depend = new JarDependencies(myJarFile);
   JarDependencies anotherDepend = new JarDependencies(aSecondJarFile);
   boolean isDependingOn = depend.isDependingOn(anotherDepend);
