Detailed Description

template<typename _T_>
class knowCore::QuantityValue< _T_ >

This class can be use to combine a number with a Unit. Look at UnitNumber for an alias combining BigNumber with Unit.

◆ fromRdfLiteral()

template<typename _T_ >
cres_qresult< QuantityValue< _T_ > > knowCore::QuantityValue< _T_ >::fromRdfLiteral ( const QString & _value,
const DeserialisationContexts & _context = defaultDeserialisationContext() )
inlinestatic

Convert from a rdf literal (something like "12.0 m/s")

◆ md5()

template<typename _T_ >
cres_qresult< QByteArray > knowCore::QuantityValue< _T_ >::md5 ( ) const
inline
Returns
a md5 hash of the value

◆ operator*() [1/2]

template<typename _T_ >
QuantityValue< _T_ > knowCore::QuantityValue< _T_ >::operator* ( const _T_ & _rhs) const

Multiplication.

◆ operator*() [2/2]

template<typename _T_ >
cres_qresult< QuantityValue< _T_ > > knowCore::QuantityValue< _T_ >::operator* ( const QuantityValue< _T_ > & _rhs) const
inline

Attempt a multiplication, return an error if units are not compatible

◆ operator+()

template<typename _T_ >
cres_qresult< QuantityValue< _T_ > > knowCore::QuantityValue< _T_ >::operator+ ( const QuantityValue< _T_ > & _rhs) const
inline

Attempt an addition, return an error if units are not compatible

◆ operator-()

template<typename _T_ >
cres_qresult< QuantityValue< _T_ > > knowCore::QuantityValue< _T_ >::operator- ( const QuantityValue< _T_ > & _rhs) const
inline

Attempt an substractionm, return an error if units are not compatible

◆ operator/() [1/2]

template<typename _T_ >
QuantityValue< _T_ > knowCore::QuantityValue< _T_ >::operator/ ( const _T_ & _rhs) const

Division.

◆ operator/() [2/2]

template<typename _T_ >

◆ operator<()

template<typename _T_ >
cres_qresult< bool > knowCore::QuantityValue< _T_ >::operator< ( const QuantityValue< _T_ > & _rhs) const

Compare two values for inferirority. It will return an error if the units are not compatible.

◆ operator==()

template<typename _T_ >
bool knowCore::QuantityValue< _T_ >::operator== ( const QuantityValue< _T_ > & _rhs) const

Compare two values. Note, that comparing two numbers with different unit is acceptable and will return false.
