示例1: IsClosure

if (!mol->HasClosureBondsPerceived())
mol->FindRingAtomsAndBonds();
return HasFlag(OB_CLOSURE_BOND);
}示例2: FindRotors
bool OBRotorList::FindRotors(OBMol &mol, bool sampleRingBonds)

// The GTD is the distance from atom i to every other atom j.
// Atoms on the "inside" of the molecule will have a lower GTD
// value than atoms on the "outside"
//
// The scoring will rank "inside" bonds first.
