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.
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.
