Scala example source code file (Settings.scala)

This example Scala source code file (Settings.scala) 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

boolean, booleansetting, configuration, int, intsetting, list, multistringsetting, reflection, setting, t, yposdebug, yshowsymkinds

The Settings.scala Scala example source code

package scala
package reflect
package runtime

import scala.reflect.internal.settings.MutableSettings

/** The Settings class for runtime reflection.
 *  This should be refined, so that settings are settable via command
 *  line options or properties.
 */
private[reflect] class Settings extends MutableSettings {

  trait Setting extends SettingValue { }

  class BooleanSetting(x: Boolean) extends Setting {
    type T = Boolean
    protected var v: Boolean = x
    override def value: Boolean = v
  }

  class IntSetting(x: Int) extends Setting {
    type T = Int
    protected var v: Int = x
    override def value: Int = v
  }

  class MultiStringSetting(xs: List[String]) extends Setting {
    type T = List[String]
    protected var v: List[String] = xs
    override def value: List[String] = v
  }
