Scala example source code file (PrivateWithin.scala)

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

package scala
package reflect
package internal

import java.lang.{ Class => jClass }
import java.lang.reflect.{ Member => jMember }

trait PrivateWithin {
  self: SymbolTable =>

  def propagatePackageBoundary(c: jClass[_], syms: Symbol*): Unit =
    propagatePackageBoundary(JavaAccFlags(c), syms: _*)
  def propagatePackageBoundary(m: jMember, syms: Symbol*): Unit =
    propagatePackageBoundary(JavaAccFlags(m), syms: _*)
  def propagatePackageBoundary(jflags: JavaAccFlags, syms: Symbol*) {
    if (jflags.hasPackageAccessBoundary)
      syms foreach setPackageAccessBoundary
  }

  // protected in java means package protected. #3946
  // See ticket #1687 for an example of when the enclosing top level class is NoSymbol;
  // it apparently occurs when processing v45.3 bytecode.
  def setPackageAccessBoundary(sym: Symbol): Symbol = (
    if (sym.enclosingTopLevelClass eq NoSymbol) sym
    else sym setPrivateWithin sym.enclosingTopLevelClass.owner
  )
}
