Last change on this file since f16a4b was 776b64, checked in by Frederik Heber <heber@…>, 15 years ago

Huge refactoring to make const what is const (ticket #38), continued.

  • too many changes because of too many cross-references to be able to list them up here.
  • NOTE that "make check" runs fine and did catch several error.
  • note that we had to use const_iterator several times when the map, ... was declared const.
  • at times we changed an allocated LinkedCell LCList(...) into

const LinkedCell *LCList;
LCList = new LinkedCell(...);

  • also mutable (see ticket #5) was used, e.g. for molecule::InternalPointer (PointCloud changes are allowed, because they are just accounting).

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.
