Member Function Documentation

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

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

void Units_UnitsSystem::Activates ( )

Activates the first unit of all defined system quantities.

TCollection_AsciiString Units_UnitsSystem::ActiveUnit ( const Standard_CString  aquantity) const

Returns for <aquantity> the active unit.

Handle< TColStd_HSequenceOfInteger > Units_UnitsSystem::ActiveUnitsSequence ( ) const

Returns a sequence of integer in correspondance with the sequence of quantities, which indicates, for each redefined quantity, the index into the sequence of units, of the active unit.

Standard_Real Units_UnitsSystem::ConvertSIValueToUserSystem ( const Standard_CString  aquantity,
const Standard_Real  avalue 
) const

Standard_Real Units_UnitsSystem::ConvertUserSystemValueToSI ( const Standard_CString  aquantity,
const Standard_Real  avalue 
) const

Converts the real value <avalue> from the user system of units to the S.I. system of units. <aquantity> is the physical dimensions of the measurement.

Standard_Real Units_UnitsSystem::ConvertValueToUserSystem ( const Standard_CString  aquantity,
const Standard_Real  avalue,
const Standard_CString  aunit 
) const

Converts a real value <avalue> from the unit <aunit> belonging to the physical dimensions <aquantity> to the corresponding unit of the user system.

void Units_UnitsSystem::Dump ( ) const
Standard_Boolean Units_UnitsSystem::IsEmpty ( ) const

Returns TRUE if no units has been defined in the system.

Handle< Units_QuantitiesSequence > Units_UnitsSystem::QuantitiesSequence ( ) const

Returns the sequence of refined quantities.

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

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

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

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