Scala pickle data visualizer

Running application

Diagram rendering is done with Graphviz tool. It should be installed and available in command line.

Demo

There are two demo classes (TestClass1, TestClass2) provided. In order to generate diagrams for them you can use run-demo.sh script.

Custom class file

run.sh classpath class_name

Pickle format

Information taken from scala.reflect.PickleFormat.
