Scala example source code file (GenPositions.scala)

This example Scala source code file (GenPositions.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.)

The GenPositions.scala Scala example source code

package scala.reflect.reify
package codegen

trait GenPositions {
  self: Reifier =>

  import global._

  // we do not reify positions because this inflates resulting trees, but doesn't buy as anything
  // where would one use positions? right, in error messages
  // but I can hardly imagine when one would need a position that points to the reified code
  // usually reified trees are used to compose macro expansions or to be fed to the runtime compiler
  // however both macros and toolboxes have their own means to report errors in synthetic trees
  def reifyPosition(pos: Position): Tree =
    reifyMirrorObject(NoPosition)
}
