Constructor Detail

OrganicMoleculeBuilder

public OrganicMoleculeBuilder(int setCoreCarbons)

Creates an organic molecule builder.

Parameters:

setCoreCarbons - The number of core carbons.

Method Detail

addSubstituent

public OrganicMoleculeBuilder addSubstituent(int position,
                                             OrganicMoleculeBuilder.Substituent substituent)

Adds a substituent to the backbone at the given position.

Parameters:

position - The position.

substituent - The new substituent.

Returns:

This builder.

getSubstituents

public OrganicMoleculeBuilder.Substituent[] getSubstituents(int position)

Parameters:

position - The carbon in the base.

Returns:

An array containing the carbon's substituents.

getCoreCarbons

public int getCoreCarbons()

Gets the number of carbons in the base chain/cycle of this molecule.

Returns:

The number of core carbons.

finishBackbone

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

Completes the backbone as appropriate for the type of builder.

Parameters:

first - The first backbone carbon.
