Services to manage units conversion between Front-ends and Engines.
This conversion is managed by a table of correspondance between the quantities
and their "conversion coefficient".
This table is implemented like an external array (TCollection_Array1) regarding
to the quantities enumeration.

DEFINE_STANDARD_ALLOC | Quantity_Convert () |
Creates an object; | |
Static Public Member Functions | |
static void | SetQuantity (const Quantity_PhysicalQuantity aQuantity, const Quantity_Coefficient aCoef) |
Updates the conversion table (correspondances between Quantities and conversion coefficients). | |
static Standard_Real | ConvertUserToSI (const Quantity_PhysicalQuantity aQuantity, const Standard_Real aVal) |
Converts, from the conversion table, the value <aVal> from the user system to the SI system. | |
static Standard_Real | ConvertSIToUser (const Quantity_PhysicalQuantity aQuantity, const Standard_Real aVal) |
Converts, from the conversion table, the value <aVal> from the SI system to the user system. | |
static Standard_Boolean | IsPhysicalQuantity (const TCollection_AsciiString &aTypeName, TCollection_AsciiString &anEnum) |
if (aType is a physical quantity) returns True and the name of the associated PhysicalQuantity . else returns False. |
