Detailed Description

template<unsigned NUM_EVENTS, class CONCRETE>
class GenericEventHandler< NUM_EVENTS, CONCRETE >

A generic base class providing the functionality for timing various events. Subclasses provide the event codes and names; see HeartEventHandler for an example.

Note: this class assume that, for any given concrete class, the last event represents the total time, and thus wraps all other events.

The methods in this class are not implemented separately as then they would not be inline, which could impact performance; we generally want timing routines to be very lightweight.

static double GenericEventHandler< NUM_EVENTS, CONCRETE >::GetCpuTime (  )  [inline, static, private]
template<unsigned NUM_EVENTS, class CONCRETE>
static double GenericEventHandler< NUM_EVENTS, CONCRETE >::GetElapsedTime ( unsigned  event  )  [inline, static]

Get the time (in milliseconds) accounted so far to the given event.

Will automatically determine if the event is currently ongoing or not.

Parameters:
event the index of an event (this must be less than NUM_EVENTS)

Check whether the event handler is enabled.

Definition at line 380 of file GenericEventHandler.hpp.

template<unsigned NUM_EVENTS, class CONCRETE>
static void GenericEventHandler< NUM_EVENTS, CONCRETE >::MilliSleep ( unsigned  milliseconds  )  [inline, static, private]

Sleep for a specified number of milliseconds Used in testing Ought to be more portable than sleep() or usleep().

Parameters:
milliseconds minimim number of milliseconds for which to sleep (ought to be a multiple of 10)

Definition at line 72 of file GenericEventHandler.hpp.

template<unsigned NUM_EVENTS, class CONCRETE>
static void GenericEventHandler< NUM_EVENTS, CONCRETE >::Report (  )  [inline, static]

Print a report on the timed events and reset the handler.

Assumes all events have ended.

If there is a collection of processes then the report will include an average and maximum over all CPUs.

template<unsigned NUM_EVENTS, class CONCRETE>
static void GenericEventHandler< NUM_EVENTS, CONCRETE >::Reset (  )  [inline, static]

Reset the event handler - set all event durations to zero.
