static void | UnitsFile (const Standard_CString afile) |
Defines the location of the file containing all the information useful in creating the dictionary of all the units known to the system. More... | |
static void | LexiconFile (const Standard_CString afile) |
Defines the location of the file containing the lexicon useful in manipulating composite units. More... | |
static Handle < Units_UnitsDictionary > | DictionaryOfUnits (const Standard_Boolean amode=Standard_False) |
Returns a unique instance of the dictionary of units. If <amode> is True, then it forces the recomputation of the dictionary of units. More... | |
static Handle< Units_Quantity > | Quantity (const Standard_CString aquantity) |
Returns a unique quantity instance corresponding to <aquantity>. More... | |
static Standard_CString | FirstQuantity (const Standard_CString aunit) |
Returns the first quantity string founded from the unit <aUnit>. More... | |
static Handle< Units_Lexicon > | LexiconUnits (const Standard_Boolean amode=Standard_True) |
Returns a unique instance of the Units_Lexicon. If <amode> is True, it forces the recomputation of the dictionary of units, and by consequence the completion of the Units_Lexicon. More... | |
static Handle< Units_Lexicon > | LexiconFormula () |
Return a unique instance of LexiconFormula. More... | |
static Handle< Units_Dimensions > | NullDimensions () |
Returns always the same instance of Dimensions. More... | |
