Constructor & Destructor Documentation

MOERTEL::Function::Function (  int  outlevel, MOERTEL::Function::FunctionType  type )  [inline]

Constructor. Constructs an instance of this base class. Parameters: outlevel  : Level of output information written to stdout ( 0 - 10 ) type  : Function type

MOERTEL::Function::Function (  const MOERTEL::Function &  old  )  [inline]

Copy-Constructor. Makes a deep copy Parameters: old  : Instance to be copied

Member Function Documentation

virtual MOERTEL::Function* MOERTEL::Function::Clone (   )  const [pure virtual]

Clone method. The derived class implementing this virtual method is supposed to make a deep copy of itself and return a pointer to the copy. Implemented in MOERTEL::Function_Constant1D, MOERTEL::Function_Linear1D, MOERTEL::Function_DualLinear1D, MOERTEL::Function_LinearTri, MOERTEL::Function_DualLinearTri, and MOERTEL::Function_ConstantTri.

virtual bool MOERTEL::Function::EvaluateFunction (  const MOERTEL::Segment &  seg, const double *  xi, double *  val, const int  valdim, double *  deriv )  [pure virtual]

Evaluate the function and derivatives at a given local coordinate. Parameters: xi  (in) : Local coordinate where to evaluate the function val  (out) : Function values at xi valdim  (in) : Dimension of val deriv  (out) : Derivative of functions at xi Implemented in MOERTEL::Function_Constant1D, MOERTEL::Function_Linear1D, MOERTEL::Function_DualLinear1D, MOERTEL::Function_LinearTri, MOERTEL::Function_DualLinearTri, and MOERTEL::Function_ConstantTri.
