Instrumentation

object Instrumentation

An object that controls profiling of instrumented byte-code. The instrumentation is achieved by using java.lang.instrument package. The instrumentation agent can be found in scala.tools.partest.javaagent 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 canonical way of using instrumentation is have a test-case in files/instrumented directory. The following code in main:

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

should print:

true
Method call statistics:
scala/Predef$.println(Ljava/lang/Object;)V: 1
