Detailed Description

Unit conversion class to convert values between physical unit systems.

An object of this class can be configured to convert values of a physical unit between 2 physical unit systems. An angle value given in degrees can e.g. be converted from/to radians or vice versa by an object of this class.

Constructor & Destructor Documentation

cUnitConverter::cUnitConverter ( char const *  _kind,
char const *  _name,
char const *  _symbol,
double  _factor = 1.0,
double  _offset = 0.0,
int  _decimal_places = 1 
)

Constructor of cUnitConverter class.

At construction time the conversion parameters - a factor and an offset - must be provided along with elements that describe the unit of a value

Parameters:
_kind- a string describing the kind of unit to be converted (something like "angle" or "time")
_name- the name of the external unit (something like "degrees" or "milliseconds")
_symbol- the symbol of the external unit (something like "deg" or "ms")
_factor- the conversion factor from internal to external units
_offset- the conversion offset from internal to external units
_decimal_places- A usefull number of decimal places for printing values in the external unit system
Attention:
The strings given _kind, _name and _symbol are NOT copied, just their address is stored

Member Function Documentation

int cUnitConverter::GetDecimalPlaces ( void  ) const

Return the number of decimal places for printing values in the external unit system.

double cUnitConverter::GetFactor ( void  ) const

Return the conversion factor from internal to external units.

char const* cUnitConverter::GetKind ( void  ) const

Return the kind of unit converted (something like "angle" or "time")

char const* cUnitConverter::GetName ( void  ) const

Return the name of the external unit (something like "degrees" or "milliseconds")

double cUnitConverter::GetOffset ( void  ) const

Return the conversion offset from internal to external units.

char const* cUnitConverter::GetSymbol ( void  ) const

Return the symbol of the external unit (something like "deg" or "ms")

double cUnitConverter::ToExternal ( double  internal) const

Convert single value internal given in internal units into external units. Returns internal * factor + offset

Convert values in simple array internal, each given in internal units into external units. Returns a simple array with each valid element converted with internal[i] * factor + offset

Only valid entries of the internal vector are converted.

std::vector<double> cUnitConverter::ToExternal ( std::vector< double > const &  internal) const

Convert values in vector internal, each given in internal units into external units. Returns a vector with each element converted with internal[i] * factor + offset

double cUnitConverter::ToInternal ( double  external) const

Convert value external given in external units into internal units. Returns (external - offset) / factor

Convert values in simple array external, each given in external units into internal units. Returns a simple array with each valid element converted with external[i] * factor + offset

Only valid entries of the external vector are converted.

std::vector<double> cUnitConverter::ToInternal ( std::vector< double > const &  external) const

Convert values in vector external, each given in external units into internal units. Returns a vector with each valid element converted with external[i] * factor + offset
