Scala example source code file (Perf.java)

This example Scala source code file (Perf.java) is included in my "Source Code Warehouse" project. The intent of this project is to help you more easily find Scala source code examples by using tags.

All credit for the original source code belongs to scala-lang.org; I'm just trying to make examples easier to find. (For my Scala work, see my Scala examples and tutorials.)

Scala tags/keywords

actor, perf, thread, threadpool

The Perf.java Scala example source code

package scala.actors.threadpool;

/**
 * Compilation stub for pre-1.4.2 JREs. Thanks to it, the whole backport
 * package compiles and works with 1.4.2 as well as wih earlier JREs, and takes
 * advantage of native Perf class when running on 1.4.2 while seamlessly
 * falling back to System.currentTimeMillis() on previous JREs. This class
 * should NOT be included in the binary distribution of backport.
