this labeller uses slow data structures and has been replaced - Canon

Canonically labels an atom container implementing the algorithm published in David Weininger et al. [Weininger, David et. al.. Journal of Chemical Information and Computer Sciences. 1989. 29]. The Collections.sort() method uses a merge sort which is stable and runs in n log(n).

    Canonically label the fragment. The labels are set as atom property InvPair.CANONICAL_LABEL of type Integer, indicating the canonical order. This is an implementation of the algorithm published in David Weininger et.al. [Weininger, David et. al.. Journal of Chemical Information and Computer Sciences. 1989. 29].
    The Collections.sort() method uses a merge sort which is stable and runs in n log(n).
    It is assumed that a chemically valid AtomContainer is provided: this method does not check the correctness of the AtomContainer. Negative H counts will cause a NumberFormatException to be thrown.
    
    Parameters:
    
    atomContainer - The molecule to label
