Detailed Description

template<class TimeType>
class Rythmos::TimeRange< TimeType >

Represent a time range.

The compiler-generated default constructor, copy constructor, and assignment operators are allowed and perform correctly.

ToDo: Put in checks for the range if needed.

Friends And Related Symbol Documentation

◆ compareTimeValues()

template<class TimeType>
int Rythmos::compareTimeValues ( const TimeType & t1,
const TimeType & t2 )
related

Compare two times taking into account floating point errors.

Returns
Return -1 if t1 < t2 , 0 if t1 == t2 and +1 if t1 > t2 .

Note that this function compares t1 to t2 and not the other way around.

This function is designed to solve the problem where in:

const TimeType timeStep = endTime - time;
const TimeType updatedEndTime = time + timeStep;
const bool isAtOrPastEndTime = ( updatedEndTime >= endTime );

the bool isAtOrPastEndTime may actually be false! This is especially a danger if IEEE floating point numerics are not being used (and there are many systems that do not for speed and other reasons).
