Enclosing class:

ThreadWatchdog

public static final class ThreadWatchdog.ActivityTracker
extends AtomicLong

Per-thread class which keeps track of activity on that thread, represented as a long which is incremented every time an activity starts or stops. Thus the parity of its value indicates whether the thread is idle or not. Crucially, the activity tracking is very lightweight (on the tracked thread).
