Using the Class Dependency Analyzer for OODT By Joshua Garcia
Motivation • A software system has many dependencies • Programming language level • Finding relevant dependencies • Displaying dependencies in an understandable form • Usable • Simple
Motivation – iRODS - Prescriptive Source: https://www.irods.org/index.php/Introduction_to_iRODS
Overview • Class Dependency Analyzer (CDA) • Find dependencies • Visualize them • Relatively Usable and Simple • Granularity • Package, class, jar, directory structure
Compiling OODT • You will need Apache Maven • Please refer to the Maven website about how to install Maven • Maven will need to download dependencies • Compiling all of OODT takes long • If you want try compiling all of OODT, going to the top directory containing all the source directories and a pom.xml file and type • mvn install • You can change to each source directory in the OODT tar.gz file that has a pom.xml and use the following command to compile • mvn install • Compiling with Maven • Go to the core directory of OODT and type “mvn install” without the quotes
Installation of CDA • Unzip the archive pf-cda-x.x.zip to any directory you want. • Then ensure that environment variable JAVA_HOME is set to a Java Runtime Environment 1.5.0 or higher. • Open a command shell in the directory to which you unzipped the archive. • Run the script sssgen.bat or sssgen.sh to generate a start shell script that invokes the tool with absolute classpath entries in order to allow to start it from anywhere in the file system. • Eventually a run.bat (or run.sh on Linux) must be available in the directory Source: http://www.dependency-analyzer.org/#QuickStart
Importing Source to Analyze • File->New • Workset Wizard dialog appears • In the General tab, enter a Name in the associated text box • In the Classpath tab, click the add button • Can select jar, Eclipse .classpath file, folder containing .class files • Display Filter tab and Ignore Filter tab • Filter out package patterns • Once you click the save button in the Workset Wizard, you will be asked to save your workset.
Highlighted Features • Find • All dependents • Direct dependents • All implementors • …. • Graphs that show all dependencies between two classes • Show dependency, graph, or hierarchy view for selected elements • Tabular views of dependencies • Copy and paste to text • Different icons for different kinds of entities • Finding main methods • Right click on the workset row or icon • Find duplicate classes • Circular dependencies • Doesn’t seem to work
