Provide information about selected face.
This routine is passed into any observer/action set routine which refers to a face, so routines like touchFaceFirstTime(). It provides you with information about the particular face as well as their location within the mesh.

| int peano4::datamanagement::FaceMarker::getSelectedFaceNumber | ( | ) | const |
Return the number of the face.
If you use the modulo Dimensions, then you implicitly know along which coordinate axis the corresponding face normal points.

| bool peano4::datamanagement::FaceMarker::hasBeenRefined | ( | ) | const |
Has a face been refined.
We do not really refine faces. We refine cells. Cells in turn are refined if and only if one of their adjacent vertices holds a refine flag. Consequently, if one vertex adjacent to a face carries the refine flag, the face will be refined as well. In this case, it is not hanging.

| tarch::la::Vector< Dimensions, double > peano4::datamanagement::FaceMarker::normal | ( | int | i | ) | const |
This operation gives you the normal of a certain face.
The orientation of the normal depends on the context in which the face marker is used: Every operation within Peano is always triggered from a cell point of view. The normal corresponds to this view. If you run through a mesh twice, and if you twice hit the same face, the normal thus might be mirrored as a face marker might be constructed from the other adjacent cell.
We do enumerate the faces as follows: The first face is the one whose normal is parallel to first coordinate axis. The second face is the one whose normal is parallel to the second axis. The d+1th face is the one parallel to the very first face. The very first face however is closer to the origin in the unit cube.

| tarch::la::Vector< Dimensions, double > peano4::datamanagement::FaceMarker::outerNormal | ( | int | i | ) | const |
This operation gives you the outer normal of a cell.
Different to normal(int), the normal however is oriented along the domain boundaries, i.e. it always points outside from the local domain.

| peano4::datamanagement::FaceMarker & peano4::datamanagement::FaceMarker::select | ( | int | face | ) |
Selects a face within a cell, i.e.
now the marker knows to which face it corresponds. After that, the routine returns a this reference.

| tarch::la::Vector< Dimensions, double > peano4::datamanagement::FaceMarker::x | ( | ) | const |
A marker is always tied to one particular face.
You can still get the data of all faces of a cell (see x(int)), but this particular function gives you the x coordinate with the centre of the currently selected face.
