Detailed Description

DtTimedSection are objects used to measure a section of time.

The time measured is between the start call and the stop call. Timed sections may be created on either the stack or the heap. Construction cost should be near trivial, so caching is not necessary.

CTOR.

Member Function Documentation

virtual double DtTimedSection::duration ( ) const

virtual

Get the amount of time between starts and stops.

This function should only be called once per 'measurement' as the duration calculation may take non trivial time.

Warning

This function should only be called after a start/stop pair.

Return values

The	return value is the time in seconds.

virtual void DtTimedSection::start ( )

virtual

Start timing.

virtual void DtTimedSection::stop ( )

virtual

Stop timing.
