Function Members (Methods)

This is an abstract class, constructors will not be documented.
Look at the header to check for available constructors.

virtual ~IOptions()

IOptions * Clone() const

 copy the options

void SetValue(const char* name, double val)

 generic  methods for  retrivieng options 
 set option value

{ SetRealValue(name,val);}

void SetValue(const char* name, int val)

{ SetIntValue(name,val);}

void SetValue(const char* name, const char* val)

{ SetNamedValue(name,val);}

double RValue(const char* name) const

std::string NamedValue(const char* name) const

bool GetRealValue(const char* , double& ) const

 methods to be re-implemented in the derived classes

{ return false; }

bool GetIntValue(const char* , int& ) const

{ return false; }

bool GetNamedValue(const char* , string& ) const

{ return false; }

void SetRealValue(const char* , double )

 method wich need to be re-implemented by the derived classes

{MATH_ERROR_MSG("IOptions::SetRealValue","Invalid setter method called"); }

void SetIntValue(const char* , int )

void SetNamedValue(const char* , const char* )

{MATH_ERROR_MSG("IOptions::SetNamedValue","Invalid setter method called"); }

void Print(ostream& = std::cout) const

 print options

{MATH_INFO_MSG("IOptions::Print","it is not implemented");}
