Scala example source code file (StdCreators.scala)

This example Scala source code file (StdCreators.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

apiuniverse, expr, fixedmirrortreecreator, fixedmirrortypecreator, illegalargumentexception, reflection, singleton, stdcreators, tree, type, u

The StdCreators.scala Scala example source code

package scala
package reflect
package internal

import scala.reflect.api.{TreeCreator, TypeCreator}
import scala.reflect.api.{Universe => ApiUniverse}

trait StdCreators {
  self: SymbolTable =>

  case class FixedMirrorTreeCreator(mirror: scala.reflect.api.Mirror[StdCreators.this.type], tree: Tree) extends TreeCreator {
    def apply[U <: ApiUniverse with Singleton](m: scala.reflect.api.Mirror[U]): U # Tree =
      if (m eq mirror) tree.asInstanceOf[U # Tree]
      else throw new IllegalArgumentException(s"Expr defined in $mirror cannot be migrated to other mirrors.")
  }

  case class FixedMirrorTypeCreator(mirror: scala.reflect.api.Mirror[StdCreators.this.type], tpe: Type) extends TypeCreator {
    def apply[U <: ApiUniverse with Singleton](m: scala.reflect.api.Mirror[U]): U # Type =
      if (m eq mirror) tpe.asInstanceOf[U # Type]
      else throw new IllegalArgumentException(s"Type tag defined in $mirror cannot be migrated to other mirrors.")
  }
}
