Public Member Functions
	HappyOrderEnforcer (const char *aName)
void	checkpoint ()
	resumes jobs that need resuming (if any)
void	enqueue (HappyConnOpener &)
	starts managing the job's wait; the job should expect a call back
void	dequeue (HappyConnOpener &)
	stops managing the job's wait; cancels the pending callback, if any

Public Attributes
const char *const	name
	waiting event name, for debugging

Protected Member Functions
virtual bool	readyNow (const HappyConnOpener &) const =0
virtual AsyncCall::Pointer	notify (const CbcPointer< HappyConnOpener > &)=0
bool	waiting () const
bool	startedWaiting (const HappyAbsoluteTime lastStart, const int cfgTimeoutMsec) const

Private Member Functions
void	noteWaitOver ()

Static Private Member Functions
static void	NoteWaitOver (void *raw)

Private Attributes
HappySpareWaitList	jobs_
	queued jobs waiting their turn
HappyAbsoluteTime	waitEnd_ = 0
	expected NoteWaitOver() call time (or zero)

Detailed Description

Efficiently drains a FIFO HappyConnOpener queue while delaying each "pop" event by the time determined by the top element currently in the queue. Its current cbdata-free implementation assumes static storage duration.
