virtual Sigma* gridripper::amr1d::Sigma::cloneSigma (  )  const [pure virtual]

Clones the object.

Returns:
the clone

Implemented in gridripper::amr1d::sigma::ConstantSigma, gridripper::amr1d::sigma::LStepSigma, gridripper::amr1d::sigma::VanishingSigma, and gridripper::amr1d::sigma::VaryingSigma.

static Sigma* gridripper::amr1d::Sigma::create ( const string &  cmd,
const Parameters &  param,
const PDE &  pde 
) throw (IllegalArgumentException&) [static]

Instantiates a Sigma implementation.

Parameters:
cmd the class name and arguments
param the parameters
pde the PDE
Returns:
the Sigma instance
virtual GReal_t gridripper::amr1d::Sigma::getValue ( GReal_t  x,
int  ileft,
int  iright 
) const [pure virtual]

Gets the value of the numerical dissipation factor in the specified point.

Parameters:
x the x coordinate
ileft point index relative to the left bound (positive or zero) if the current grid contains the left bound, numeric_limits<int>::max() otherwise.
iright point index relative to the right bound (negative or zero) if the current grid contains the right bound, numeric_limits<int>::min() otherwise

Implemented in gridripper::amr1d::sigma::ConstantSigma, gridripper::amr1d::sigma::LStepSigma, gridripper::amr1d::sigma::VanishingSigma, and gridripper::amr1d::sigma::VaryingSigma.
