[Cdk-user] IRingSet interface question

[Bala B K <bk...@gm...>]

Hello,

I was looking at the IRingSet interface and was wondering why
getRings(IAtom) and getRings(IBond) return different types.
getRings(IAtom) returns an IRingSet of all the rings that the atom
belongs to but getRings(IBond) returns a List of all rings that the
bond belongs to, instead of returning an IRingSet. It would be nice to
have the same return type for both functions.

I am using CDK version 1.0.3 with Java 1.5.

Thanks,
Bala.
