Object-oriented metrics for Java programs ProjectinComputerScience–EDAN70 January22,2015. Tools cannot. To know that a package in your project is. What follows is a brief description of the object oriented design quality metrics mentioned in [4]. The paper defines. Used to evaluate object-oriented environments at the beginning of the object oriented design revolution. However, raditional metrics for procedural approaches are not adequate for evaluating object oriented software, primarily because they are not designed to measure basic elements like classes, objects, polymorphism, and message-passing.

JaSoMe: Java Source Metrics Jasome (JAH-suhm, rhymes with awesome) is a source code analyzer that mines internal quality metrics from projects based on source code alone. This distinguishes Jasome from similar tools by not requiring the project first be compiled, or even compilable. Most analyzers only work on projects that successfully compile, which in the case of Java projects means all dependencies must be satisfied, any external libraries are properly on the classpath, any code generation utilities must properly run, and so on. However, when all you need is the quality metrics for Java source code, this compilation requirement is unnecessary since most metrics can be derived from the source code alone. 
Jasome scans a given directory for.java files and performs Best Guess Metrics Analysis to derive various quality metrics, and then outputs those metrics on a a per-file basis as XML.
Each XML output will contain the name/path of the file analyzed, and the values of its per-class and per-method metrics. It will also list directory structures and their per-package metrics. Best Guess Metrics Analysis means Jasome will continue collecting metrics even when individual files make it difficult. When code references methods or objects defined in dependencies that may or may not be on the class path, Jasome will assume those dependencies are present and properly compilable. If Jasome cannot make a clear determination for analysis, it will make a best guess and output metrics whose values are as close as possible to the actual metrics values one would achieve if analyzing the data with a metrics engine that relies on proper compilation. When a java class is syntactically invalid and would not compile, Jasome will either skip the offending methods or classes, or skip the file entirely but continue processing the remaining files.
In other words, there are definitely ways someone can manipulate their code to intentionally change the measurements for metrics, but by and large on a normal project Jasome will be accurate. Getting Started Download the latest distribution and unzip, change into directory, then run: bin/jasome JaSoMe will gather metrics and output them to the console. You can save the XML to a file using the --output option. Metrics Jasome is either currently tracking or planning to track the following metrics: • Raw Total Lines of Code (RTLOC) - The actual number of lines of code in a class, using the line numbers of the file itself. Comments, whitespace, and everything else is counted.
