Finding a good way to reverse engineering or trace cod
Hi.
I'm pretty new to IntelliJ. I was always wondering if there is something like that I describe below:
I'm looking for a tool that will write or display diagram or anything else of functions that I'm invoking. Let's say I have an application combined with a device that does something, for example it's scanning a barcode. I have all programmed and when I scan application prints me that code on the console. However this application is far more complex than this - there are plenty of things done from the scanning to printing result. The device can do plenty of more things. And is there anyway to trace it because I don't know the code very well and documentation it's not in English.
Whan I mean is:
1. When any method is invoked in application show trace of it (if possible diagram) of what was from the beggining to the end invoked (of course I only want to display project methods).
If there is no such thing what's the best way to know the code of quite large application without knowing it - I've just have it up and running.
It can be usefull for everything - like when you do a web page and this webpage invoke something in your app display trace of it.
I don't know if I desribed it clearly enough - so ask any question I will try to describe it better.
p.s. sorry for language mistakes - spelling inspection does not work in there.

Hello Gal,
No, there's no such possibility, like "total tracing"
I'm afraid in case you get the trace you want, it would be difficult to get use of it: there would be tonns of method calls, possibly from different threads.
What you can do with IntelliJ IDEA for reverse engineering is, for selected set of methods:
- Navigate -> Call Hierarchy action (you're provided with the method call tree)
- Also, you can create debugger breakpoints with "Suspend=no" and "Log evaluated expression"
Hi Irina,
Yes. I though there will be no such tool - about calling plenty of classes, etc. you could always provide some kind of skipping, like in debugger (javax.*).
Sorry - I'm very new to Intellij - can you provide me an further explenation or link for HowTo??
Hello,
Please check this reference page for the available breakpoint options.
Hint: you can left-click on the editor gutter holding shift. That is a shortcut for setting no-suspend breakpoint and starting configuring its message:
