progress

Package progress contains tools for reporting progress of computations. Classes can report progress extending trait net.sf.ij_plugins.ui.progress.ProgressReporter. Progress can be observed extendfing trait net.sf.ij_plugins.ui.progress.ProgressListener.

Example usage:

class CounterWithProgress(marker: Char) extends ProgressReporter {
  def count(max: Int) {
    val progressIncrement = Math.max(max / 10, 1)

    println("Counting " + max + " '" + marker + "'.")

    for (i <- 1 to max) {
      print(marker)
      if (i % progressIncrement == 0) notifyProgressListeners(i, max)
    }

    println("\nCounting done.")
  }
}

object ProgressReporterExample extends App {
  // Create counter
  val counter = new CounterWithProgress('+')

  // Add progress listener
  counter.addProgressListener(e => println(f"\nProgress notification: ${e.progressPercent}%3.0f%%"))

  // Count
  counter.count(100)
}
