Method Detail

splitMolecule

protected static List<IAtomContainer> splitMolecule(IAtomContainer atomContainer,
                                 IBond bond)

Non destructively split a molecule into two parts at the specified bond. Note that if a ring bond is specified, the resultant list will contain teh opened ring twice.

Parameters:

atomContainer - The molecule to split

bond - The bond to split at

Returns:

A list containing the two parts of the molecule

makeAtomContainer

protected static IAtomContainer makeAtomContainer(IAtom atom,
                               List<IBond> parts,
                               IAtom excludedAtom)

traverse

protected static List<IBond> traverse(IAtomContainer atomContainer,
                   IAtom atom,
                   List<IBond> bondList)
