Member Function Documentation

virtual BSpline* sierra::nalu::BSpline::clone ( ) const

pure virtual

Copy this object and return a BSpline pointer.

This facilitates polymorphic copying given a base-class pointer or reference.

Implemented in sierra::nalu::BSpline5D, sierra::nalu::BSpline4D, sierra::nalu::BSpline3D, sierra::nalu::BSpline2D, and sierra::nalu::BSpline1D.

int sierra::nalu::BSpline::get_dimension ( ) const

inline

Query the dimensionality of this spline (number of independent variables)

References dim_, and value().

int sierra::nalu::BSpline::get_order ( ) const

inline

Query the order of accuracy for this spline.

The spline has (order-1) continuous derivatives

References order_.

BSpline& sierra::nalu::BSpline::operator= ( const BSpline &  )

private

virtual void sierra::nalu::BSpline::read_hdf5 ( H5IO &  io )

pure virtual

Read a spline from an HDF5 database.

The file should be opened and an hdf5 "group" specified. This spline will be read from the specified group.

Implemented in sierra::nalu::BSpline5D, sierra::nalu::BSpline4D, sierra::nalu::BSpline3D, sierra::nalu::BSpline2D, and sierra::nalu::BSpline1D.

Referenced by sierra::nalu::BSpline2D::clone(), sierra::nalu::BSpline3D::clone(), sierra::nalu::BSpline4D::clone(), sierra::nalu::BSpline5D::clone(), sierra::nalu::BSpline1D::get_basisfun(), sierra::nalu::HDF5Table::read_hdf5_table(), and value().

virtual double sierra::nalu::BSpline::value ( const double *  ) const

pure virtual

Evaluate the dependent variable via interpolation at the given value of the dependent variable(s).

Implemented in sierra::nalu::BSpline5D, sierra::nalu::BSpline4D, sierra::nalu::BSpline3D, sierra::nalu::BSpline2D, and sierra::nalu::BSpline1D.

Referenced by sierra::nalu::BSpline1D::clone(), sierra::nalu::BSpline2D::clone(), sierra::nalu::BSpline3D::clone(), sierra::nalu::BSpline4D::clone(), sierra::nalu::BSpline5D::clone(), get_dimension(), sierra::nalu::HDF5Table::query(), and sierra::nalu::HDF5Table::raw_query().

double sierra::nalu::BSpline::value ( std::vector< double > &  x ) const

inline

References read_hdf5(), value(), and write_hdf5().

Referenced by value().

virtual void sierra::nalu::BSpline::write_hdf5 ( H5IO &  io ) const

pure virtual

Write a spline to an HDF5 database.

The file should be opened and an hdf5 "group" created. This spline will be written to the specified group.

Implemented in sierra::nalu::BSpline5D, sierra::nalu::BSpline4D, sierra::nalu::BSpline3D, sierra::nalu::BSpline2D, and sierra::nalu::BSpline1D.
