Detailed Description

Walks from starting face around edge.

Implicit description of edge:

  • face
  • index in face. edge is always between f[index] and f[index+1]
  • direction (cell to walk into)
  1. Use in-place:
    edgeFaceCirculator circ(..);
    // Optionally rotate to beginning: circ.setCanonical();
    // Walk
    do
    {
    Info<< "face:" << circ.face() << endl;
    ++circ;
    }
    while (circ != circ.end());
  2. Use like STL iterator:
    edgeFaceCirculator circ(..);
    for
    (
    edgeFaceCirculator iter = circ.begin();
    iter != circ.end();
    ++iter
    )
    {
    Info<< "face:" << iter.face() << endl;
    }
