Instrumentation

object Instrumentation

An object that controls profiling of instrumented byte-code.

The instrumentation is achieved by using the java.lang.instrument package. The instrumentation agent can be found in the ch.epfl.lamp.instragent package.

At the moment the following classes are being instrumented: * all classes with empty package * all classes from scala package (except for classes responsible for instrumentation)

The following code in main:

import ch.epfl.lamp.grading.instrumented.Instrumentation._
def main(args: Array[String]): Unit = {
  startProfiling()
  // should box the boolean
  println(true)
  stopProfiling()
  printStatistics()
}

should print:

true
