what's the content in method jacocoInit()

[moon xxx]

I am learning the jacoco code, I ran the class "CoreTutorial", and dump the bytecode, This's what I saw in the class file

boolean[] var1 = $jacocoInit(); 

How can I see the content in method "$jacocoInit()", meanwhile, I notice there is a variable named jacocoData, but I cannot saw it in the class file.

Hi,

if you want to study byte code instrumentation done by JaCoCo I recommend to use offline instrumentation (e.g. with the cli) and decompile instrumented classes afterwards. The “CoreTutorial” instruments classes in-memory only.

Part of the content of $jacocoInit() depends on the selected runtime (See IExecutionDataAccessorGenerator implementations and https://www.jacoco.org/jacoco/trunk/doc/implementation.html)

Cheers,

File file = new File("xxxx");
FileOutputStream f = new FileOutputStream(file);
f.write(instrumented);
f.close();

I add this in class CoreTutorial method execute(), write the instrumented classes to the file then decompile it. but cannot see what's in the method jacocoInit()

Are you using javap to decompile? In this case specify options -v -c otherwise you won’t see code.
