java.lang.Object

org.openscience.cdk.stereo.Atropisomeric

All Implemented Interfaces:

Cloneable, ICDKObject, IStereoElement<IBond,IAtom>

public class Atropisomeric
extends Object

Restricted axial rotation around Aryl-Aryl bonds. The atropisomer is stored in a similar manner to ExtendedTetrahedral (and TetrahedralChirality) except instead of storing the central atom we store the sigma bond around which the rotation is restricted and the four carriers are connect to either end atom of the 'focus' bond.

 f: focus
 Ar: Aryl (carriers connected to either end of 'f')

Typical examples include BiNOL, and BiNAP.

Constructor Detail

Atropisomeric

public Atropisomeric(IBond focus,
                     IAtom[] carriers,
                     int value)

Define a new atropisomer using the focus bond and the carrier atoms.

Parameters:

focus - the focus bond

carriers - the carriers

value - the configuration IStereoElement.LEFT or IStereoElement.RIGHT

Method Detail

create

protected IStereoElement<IBond,IAtom> create(IBond focus,
                                             List<IAtom> carriers,
                                             int cfg)

numCarriers

protected static int numCarriers(int cfg)

getFocus

public F getFocus()

The focus atom or bond at the 'centre' of the stereo-configuration.

Specified by:

getFocus in interface IStereoElement<F extends IChemObject,C extends IChemObject>

Returns:

the focus

getCarriers

public List<C> getCarriers()

The carriers of the stereochemistry

Specified by:

getCarriers in interface IStereoElement<F extends IChemObject,C extends IChemObject>

Returns:

the carriers

getConfigClass

public int getConfigClass()

The configuration class of the stereochemistry.

Specified by:

getConfigClass in interface IStereoElement<F extends IChemObject,C extends IChemObject>

Returns:

configuration class

getConfigOrder

public int getConfigOrder()

The configuration order of the stereochemistry.

Specified by:

getConfigOrder in interface IStereoElement<F extends IChemObject,C extends IChemObject>

Returns:

configuration

getConfig

public int getConfig()

Access the configuration order and class of the stereochemistry.

Specified by:

getConfig in interface IStereoElement<F extends IChemObject,C extends IChemObject>

Returns:

the configuration

setConfigOrder

public void setConfigOrder(int cfg)

Set the configuration order of the stereochemistry.

Specified by:

setConfigOrder in interface IStereoElement<F extends IChemObject,C extends IChemObject>

Parameters:

cfg - the new configuration

contains

public boolean contains(IAtom atom)

Does the stereo element contain the provided atom.

Specified by:

contains in interface IStereoElement<F extends IChemObject,C extends IChemObject>

Parameters:

atom - an atom to test membership

Returns:

whether the atom is present

map

public IStereoElement<F,C> map(Map<IAtom,IAtom> atoms,
                               Map<IBond,IBond> bonds)

Map the atoms/bonds in this instance to a new stereo element using the provided atom/bond mapping. This allows the stereo element to be transferred between a cloned or aligned (i.e. isomorphic) chemical graph. If no mapping is found for a given atom or bond it is left intact. However the provided atom and bonds maps must not be null.

Specified by:

map in interface IStereoElement<F extends IChemObject,C extends IChemObject>

Parameters:

atoms - nullable atom mapping, used to convert the original atoms to their mapped counterparts

bonds - nullable bond mapping, used to convert the original bonds to their mapped counterparts

Returns:

a new stereo element in the same configuration but with atoms/bonds replaced with their mapped equivalence.

map

public IStereoElement<F,C> map(Map<IChemObject,IChemObject> chemobjs)

Specified by:

map in interface IStereoElement<F extends IChemObject,C extends IChemObject>

getBuilder

public IChemObjectBuilder getBuilder()

Returns a IChemObjectBuilder for the data classes that extend this class.

Specified by:

getBuilder in interface ICDKObject

Returns:

The IChemObjectBuilder matching this ICDKObject

setBuilder

protected void setBuilder(IChemObjectBuilder builder)

invapply
