Detailed Description

SIUnit is a Unit with baseUnits are fixed by its constructors, see SIExpnt.

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

Constructor & Destructor Documentation

openstudio::SIUnit::SIUnit	(	const SIExpnt &	exponents = `SIExpnt()`,
		int	scaleExponent = `0`,
		const std::string &	prettyString = `""`
	)

Default constructor.

Example:

SIUnit myEnergy(SIExpnt(1,2,-2),3,"J");
std::cout << myEnergy; // produces "kJ"

Parameters

[in]	exponents	holds the exponents for each base unit.
[in]	scaleExponent	exponent for scale. For instance 3 for kilo.
[in]	prettyString	optional string to use in place of standardString.

openstudio::SIUnit::SIUnit	(	const std::string &	scaleAbbreviation,
		const SIExpnt &	exponents = `SIExpnt()`,
		const std::string &	prettyString = `""`
	)

Alternate constructor.

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

SIUnit myEnergy("k",SIExpnt(1,2,-2),"J");
std::cout << myEnergy; // produces "kJ

Parameters

[in]	scaleAbbreviation	is string equal to a scale abbreviation. For instance "k" for kilo.
[in]	exponents	holds the exponents for each base unit.
[in]	prettyString	optional string to use in place of standardString.
