Scala: importing object in the same file with a different name

Question

Lets say I have in the same file:

object x {
  case object z
}

object y {
  .. //want to internally refer to x.z as xxx.z
}

In other words I need to rename an import of an object in the same file.

currently I resort to:

object y {
  import x
  val xxx=x
  .. //referring to x.z as xxx.z
}

is there a better way of doing this? perhaps something along the lines of:

import .{x->xxx}

Answer 1

In Scala, you can rename imports like this:

import package.{x => xxx}

See here for more details: http://blog.bruchez.name/2012/06/scala-tip-import-renames.html

EDIT: from comment below

If you are in the same file - you don't need to import anything:

object X {
  val a = 5
}

object Y {
  val x = X
  def p = println(x.a)
}

Y.p

Outputs

5

Answer 2

Yes, you can do it like this:

package packagename

object x {
    case object z
}

object y {
    import packagename.{x => xxx}
    xxx.z
}

Note that you cannot import something that resides in the default package.

Answer 3

I came to the conclusion that for the proposes of what I was trying to do here, package object were really more appropriate as x only plays the role of organising the hierarchy. See here .
