•  class StampedLockWithHandle extends AnyRef

  A stamped lock that allows passing around a lock handle to better guard methods that should only be called with an active lock.

  A stamped lock that allows passing around a lock handle to better guard methods that should only be called with an active lock.

  For example:

  object Foo {
    val lock = new StampedLockWithHandle()
  
    def bar() = lockWithWriteLockHandle { implicit writeLock =>
      // do something
      baz()
      // do more stuff
    }
  
    def baz()(implicit writeLockHandle: lock.WriteLockHandle) = {
      // do some more stuff
    }
  }

  In the above example, baz cannot be called unless a write lock was acquired specifically only with lock.
