scalajs-fake-weakreferences

scalajs-fake-weakreferences provides compatibility stubs for java.lang.ref.* APIs in Scala.js. It preserves the support that was available in Scala.js core previous to v1.6.0.

The various References provided by scalajs-fake-weakreferences do not behave correctly. They always act as strong references.

scalajs-fake-weakreferences should only be used if upgrading to Scala.js v1.6.0+ causes linking errors about java.lang.ref.* in an existing application. New applications should avoid this library.

Usage

Add the following dependency to your project settings:

libraryDependencies += ("org.scala-js" %%% "scalajs-fake-weakreferences" % "1.0.0").cross(CrossVersion.for3Use2_13)

When using a crossProject, add the above in .jsSettings(...).

You can then use the classes defined in java.lang.ref.*. Keep in mind that they will hold strong references, which will prevent the target objects from beging garbage-collected.
