Extended class LinkedCell to handle a relative offset to current cell.
  • Property mode set to 100644

1/*
2 * linkedcell.hpp
3 *
4 * If the linked cell should be usable, the class has to inherit LCNodeSet and the nodes (containing the Vectors) have to inherit LCNode. This works well
5 * for molecule and atom classes.
