A class that stores all of the mapping related data used in FEValues, FEFaceValues, and FESubfaceValues objects. Objects of this kind will be given as output argument when FEValues::reinit() calls Mapping::fill_fe_values() for a given cell, face, or subface.
The data herein will then be provided as input argument in the following call to FiniteElement::fill_fe_values().

| void internal::FEValuesImplementation::MappingRelatedData< dim, spacedim >::initialize | ( | const unsigned int | n_quadrature_points, |

| std::size_t internal::FEValuesImplementation::MappingRelatedData< dim, spacedim >::memory_consumption | ( | ) | const |
Compute and return an estimate for the memory consumption (in bytes) of this object.

| std::vector<double> internal::FEValuesImplementation::MappingRelatedData< dim, spacedim >::JxW_values |
Store an array of weights times the Jacobi determinant at the quadrature points. This function is reset each time reinit() is called. The Jacobi determinant is actually the reciprocal value of the Jacobi matrices stored in this class, see the general documentation of this class for more information.
However, if this object refers to an FEFaceValues or FESubfaceValues object, then the JxW_values correspond to the Jacobian of the transformation of the face, not the cell, i.e. the dimensionality is that of a surface measure, not of a volume measure. In this case, it is computed from the boundary forms, rather than the Jacobian matrix.
