Scala example source code file (compileTimeOnly.scala)

This example Scala source code file (compileTimeOnly.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 compileTimeOnly.scala Scala example source code

package scala.annotation

import scala.annotation.meta._

/**
 * An annotation that designates that an annottee should not be referred to after
 * type checking (which includes macro expansion).
 *
 * Examples of potential use:
 *   1) The annottee can only appear in the arguments of some other macro
 *      that will eliminate it from the AST during expansion.
 *   2) The annottee is a macro and should have been expanded away,
 *      so if hasn't, something wrong has happened.
 *      (Comes in handy to provide better support for new macro flavors,
 *      e.g. macro annotations, that can't be expanded by the vanilla compiler).
 *
 * @param  message the error message to print during compilation if a reference remains
 *                 after type checking
 * @since  2.11.0
