Detailed Description

Part of an expressions that contains a unit.

Constructor & Destructor Documentation

◆ UnitExpression()

UnitExpression::UnitExpression	(	const App::DocumentObject *	_owner = `0`,
		const Base::Quantity &	_quantity = `Base::Quantity()`,
		const std::string &	_unitStr = `std::string()`
	)

◆ ~UnitExpression()

UnitExpression::~UnitExpression ( )

Member Function Documentation

◆ getQuantity()

const Base::Quantity& App::UnitExpression::getQuantity ( ) const

◆ getScaler()

double App::UnitExpression::getScaler ( ) const

◆ getUnit()

const Base::Unit& App::UnitExpression::getUnit ( ) const

◆ getUnitString()

const std::string App::UnitExpression::getUnitString ( ) const

◆ getValue()

double App::UnitExpression::getValue ( ) const

Referenced by App::ExpressionParser::parseUnit().

◆ setQuantity()

void UnitExpression::setQuantity ( const Base::Quantity & _quantity )

◆ setUnit()

void UnitExpression::setUnit ( const Base::Quantity & _quantity )

Set unit information.

Parameters

_unit	A unit object
_unitstr	The unit expressed as a string
_scaler	Scale factor to convert unit into internal unit.

◆ simplify()

Expression * UnitExpression::simplify ( ) const

overridevirtual

Simplify the expression.

In this case, a NumberExpression is returned, as it cannot be simplified any more.

Implements App::Expression.

Reimplemented in App::VariableExpression, App::FunctionExpression, App::OperatorExpression, and App::NumberExpression.

References App::Expression::owner.
