Since the project_to_all_faces() and project_to_all_subfaces() functions chain together the quadrature points and weights of all projections of a face quadrature formula to the faces or subfaces of a cell, we need a way to identify where the starting index of the points and weights for a particular face or subface is. This class provides this: there are static member functions that generate objects of this type, given face or subface indices, and you can then use the generated object in place of an integer that denotes the offset of a given dataset.

Default constructor. This doesn't do much except generating an invalid index, since you didn't give a valid descriptor of the cell, face, or subface you wanted.
Definition at line 453 of file qprojector.h.

This is the real constructor, but it is private and thus only available to the static member functions above.
Definition at line 446 of file qprojector.h.

static |
Static function to generate the offset of a cell. Since we only have one cell per quadrature object, this offset is of course zero, but we carry this function around for consistency with the other static functions.
Definition at line 461 of file qprojector.h.
|
static |
Static function to generate an offset object for a given face of a cell with the given face orientation, flip and rotation. This function of course is only allowed if dim>=2
, and the face orientation, flip and rotation are ignored if the space dimension equals 2.
The last argument denotes the number of quadrature points the lower-dimensional face quadrature formula (the one that has been projected onto the faces) has.
Definition at line 1349 of file qprojector.cc.
|
static |
Static function to generate an offset object for a given face of a cell with the given combined face orientation. This function of course is only allowed if dim>=2
, and combined_orientation
is ignored if the space dimension equals 2.
n_quadrature_points
is the number of quadrature points the lower-dimensional face quadrature formula (the one that has been projected onto the faces) has.
Definition at line 1368 of file qprojector.cc.

static |
Compute an offset object for the given face number and orientation, taking into account the possibility of different quadrature rules being used on each face.

static |
Static function to generate an offset object for a given subface of a cell with the given face orientation, flip and rotation. This function of course is only allowed if dim>=2
, and the face orientation, flip and rotation are ignored if the space dimension equals 2.
The last but one argument denotes the number of quadrature points the lower-dimensional face quadrature formula (the one that has been projected onto the faces) has.
Through the last argument anisotropic refinement can be respected.

Conversion operator to an integer denoting the offset of the first element of this dataset in the set of quadrature formulas all projected onto faces and subfaces. This conversion operator allows us to use offset descriptor objects in place of integer offsets.
