A lightweight interface wrapping a property contained in some unspecified map.
class ShutdownHookThread extends Thread

A minimal Thread wrapper to enhance shutdown hooks.
class SystemProperties extends AbstractMap[String, String] with Map[String, String]

object SystemProperties

The values in SystemProperties can be used to access and manipulate designated system properties.
def addShutdownHook(body: ⇒ Unit): ShutdownHookThread

Register a shutdown hook to be run when the VM exits.
Register a shutdown hook to be run when the VM exits. The newly created thread is marked as a daemon so it will not interfere with VM shutdown. The hook is automatically registered: the returned value can be ignored, but is available in case the Thread requires further modification. It can also be unregistered by calling ShutdownHookThread#remove().
Note that shutdown hooks are NOT guaranteed to be run.
body
the body of code to run at shutdown
returns
the Thread which will run the shutdown hook.
def allThreads(): IndexedSeq[Thread]

Returns all active thread in the current thread's thread group and subgroups.
Returns all active thread in the current thread's thread group and subgroups.
returns
an IndexedSeq containing the threads.
def env: Map[String, String]

returns
