com.swoval.runtime.ShutdownHooks

public class ShutdownHooks
extends java.lang.Object

Provides an api for adding shutdown hooks. This exists because there is no Runtime.addShutdownHook(java.lang.Thread) implementation available on scala.js. The hooks may be added with a priority that controls the order in which the hooks run. Lower values run first.
