| Interface_FloatWriter (const Standard_Integer chars=0) | |
| Creates a FloatWriter ready to work, with default options -. More... | |
| void | SetFormat (const Standard_CString form, const Standard_Boolean reset=Standard_True) |
| Sets a specific Format for Sending Reals (main format) (Default from Creation is "%E") If <reset> is given True (default), this call clears effects of former calls to SetFormatForRange and SetZeroSuppress. More... | |
| void | SetFormatForRange (const Standard_CString form, const Standard_Real R1, const Standard_Real R2) |
| Sets a secondary Format for Real, to be applied between R1 and R2 (in absolute values). A Call to SetRealForm cancels this secondary form if <reset> is True. (Default from Creation is "%f" between 0.1 and 1000.) Warning : if the condition (0. <= R1 < R2) is not fulfilled, this secondary form is canceled. More... | |
| void | SetZeroSuppress (const Standard_Boolean mode) |
| Sets Sending Real Parameters to suppress trailing Zeros and Null Exponant ("E+00"), if <mode> is given True, Resets this mode if <mode> is False (in addition to Real Forms) A call to SetRealFrom resets this mode to False ig <reset> is given True (Default from Creation is True) More... | |
| void | SetDefaults (const Standard_Integer chars=0) |
| Sets again options to the defaults given by Create. More... | |
| void | Options (Standard_Boolean &zerosup, Standard_Boolean &range, Standard_Real &R1, Standard_Real &R2) const |
| Returns active options : <zerosup> is the option ZeroSuppress, <range> is True if a range is set, False else R1,R2 give the range (if it is set) More... | |
| Standard_CString | MainFormat () const |
| Returns the main format was C++ : return const. More... | |
| Standard_CString | FormatForRange () const |
| Returns the format for range, if set Meaningful only if <range> from Options is True was C++ : return const. More... | |
| Standard_Integer | Write (const Standard_Real val, const Standard_CString text) const |
| Writes a Real value <val> to a string <text> by using the options. Returns the useful Length of produced string. It calls the class method Convert. Warning : <text> is assumed to be wide enough (20-30 is correct) And, even if declared in, its content will be modified. More... | |
