template<class Scalar>

virtual void Tempus::Interpolator< Scalar >::setNodes ( const Teuchos::RCP< const std::vector< Teuchos::RCP< SolutionState< Scalar > > > > & nodes )

pure virtual

Store pointer to interpolation nodes.

This function represent a persisting relationship between the interpolation nodes and the interpolator. For simple interpolators like linear and Hermite, this is not needed, but for interpolators like cubic splines where there is some computational work in assembling the interpolant, this is important.

Preconditions:

nodes must have unique time values and be sorted in ascending time order

Postconditions:

If this function is called twice and nodes is a different pointer than was previously called, then it is possible that the interpolant will be recomputed when interpolate is next called.

Implemented in Tempus::InterpolatorLagrange< Scalar >.
