      public <T, E extends Exception> T profile(SupplierWithExceptionE<T,E> fn) throws E

    • child

      public IProfile child(String name)
      Description copied from interface: IProfile
      Create a child of this profile. There are three main reasons for doing this:
      • In a class, with the name of the class as the 'name'. This would often be registered as an mbean (call .registerMBean)
      • For a particular method, with the name of the method as the 'name'. Unless the class is a 'god class' with lots of 'entry level' methods in it this wouldn't normally be registered as a MBean
      • Sometimes methods are huge... 100s of lines. We can profile separate parts of this, and we can give those a name. Often this is a clue you should refactor the method!

      child in interface IProfile

    • registerMBean

      public IProfile registerMBean()
      Description copied from interface: IProfile
      The profiler is registered as a MBean. If you call it twice it will throw exceptions, so usually this is done to 'static final' profile
