Last change on this file since fc5d2d was 795c0f, checked in by Frederik Heber <heber@…>, 10 years ago

World::getAtoms() now has const versions as well.

  • this in turn required to adapt all AtomDescriptors and some fixes, e.g. predicate is now const member and works on const atom ptr.
  • Property mode set to 100644
