Class System2

  org.sonar.api.utils.System2

public class System2
extends Object

Proxy over System. It aims to improve testability of classes that interact with low-level system methods, for example :

 public class MyClass {
   private final System2 system;

   public MyClass(System2 s) {
     this.system = s;
   }

   public long xxx() {
     return system.now();
   }
 }
