Detailed Description

IPUnit is a Unit with baseUnits fixed by its constructors, see IPExpnt.

setBaseUnitExponent throws an exception if any other string is passed in as a baseUnit. IPUnit.hpp declares related operators and UnitFactory callback functions.

Constructor & Destructor Documentation

openstudio::IPUnit::IPUnit ( const IPExpnt exponents = IPExpnt(),
int  scaleExponent = 0,
const std::string &  prettyString = "" 
)

Default constructor.

Example:

IPUnit myEnergy(IPExpnt(0,1,0,0,1));
std::cout << myEnergy; // produces "ft*lb_f" 
Parameters
[in]exponentsholds the exponents for each base unit.
[in]scaleExponentexponent for scale. For instance 3 for kilo.
[in]prettyStringoptional string to use in place of standardString.
openstudio::IPUnit::IPUnit ( const std::string &  scaleAbbreviation,
const IPExpnt exponents = IPExpnt(),
const std::string &  prettyString = "" 
)

Alternate constructor.

Specify the abbreviation of the scale, rather than its exponent.

Parameters
[in]scaleAbbreviationis string equal to a scale abbreviation. For instance "k" for kilo.
[in]exponentsholds the exponents for each base unit.
[in]prettyStringoptional string to use in place of standardString.
