Class FunctionCallRecorder

java.lang.Object

com.github.beothorn.agent.recorder.FunctionCallRecorder

public class FunctionCallRecorder
extends Object

This class is responsible for recording the call stack of a function call. Usually, this should be written following OO principles of encapsulation. But this class bytecode is injected on the actual code, and having stuff private seems to cause some issues. You will see some questionable visibility choices here.
