Detailed Description

template<int dim>
class idealii::spacetime::FEJumpValues< dim >

Evaluation of the tensor-product space-time basis functions at the temporal element edges.

This class supplies the limits from above and below of the space-time basis functions by multiplying the corresponding spatial basis functions in the given spatial quadrature points by the left or right face_values of the temporal basis functions.

In practice spatial values are handled by the underlying spatial dealii::FEValues object and temporal limits are handled by the underlying temporal dealii::FEValues with two point Lobatto quadrature.
