Handle< Units_QuantitiesSequence > Units_UnitsSystem::QuantitiesSequence ( ) const

Returns the sequence of refined quantities.

◆ Remove()

void Units_UnitsSystem::Remove ( const Standard_CString  aquantity,
const Standard_CString  aunit 
)

◆ Specify()

void Units_UnitsSystem::Specify ( const Standard_CString  aquantity,
const Standard_CString  aunit 
)

Specifies for <aquantity> the unit <aunit> used.
