Detailed Description

CFMUnit is a Unit with baseUnits fixed by its constructors, see CFMExpnt.

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

Constructor & Destructor Documentation

CFMUnit() [1/2]

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

Default constructor.

Example:

CFMUnit myPower(CFMExpnt(0,0,1));
std::cout << myPower; // produces "ton" 

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.

CFMUnit() [2/2]

openstudio::CFMUnit::CFMUnit	(	const std::string &	scaleAbbreviation,
		const CFMExpnt &	exponents = CFMExpnt(),
		const std::string &	prettyString = "" )

Alternate constructor.

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

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.
