Constructor Detail

CyclicOrganicMoleculeBuilder

public CyclicOrganicMoleculeBuilder(int setCycleLength)

Creates a builder for a cyclic molecule containing the given number of carbons in the ring.

Parameters:

setCycleLength - The number (at least 3) of carbons in the ring.

Method Detail

finishBackbone

protected void finishBackbone(BondedAtom first,
                              BondedAtom[] firstBonds,
                              BondedAtom last,
                              BondedAtom[] lastBonds)

Makes the molecule cyclic by linking the first and last backbone carbons.

Specified by:

finishBackbone in class OrganicMoleculeBuilder

Parameters:

first - The first backbone carbon.

firstBonds - The first carbon's connected atoms.

last - The last backbone carbon.

lastBonds - The last carbon's connected atoms.

freeValence

protected int freeValence(int position)

Gets how many bonds a core carbon can make after inclusion in the backbone.

Specified by:

freeValence in class OrganicMoleculeBuilder

Parameters:

position - The zero-based carbon index.

Returns:

Always two, since carbons in the ring are guaranteed two links.
