public abstract class ExtraFieldInstrumenter
extends org.jetbrains.coverage.org.objectweb.asm.ClassVisitor

Instruments class with a field of the specified type. Adds initialization check into every method of the class. Required because instrumented method may be called before static initializer, e.g.

 
 public static void main(String[] args) {
  new B();
 }

 class A {
   static B b = new B();
 }

 class B extends A {
   B() {
     // called before B static initializer
   }
 }
