Constructor Detail

ExtendedCisTrans

public ExtendedCisTrans(IBond focus,
                        IBond[] peripherals,
                        int config)

Method Detail

findTerminalAtoms

public static IAtom[] findTerminalAtoms(IAtomContainer container,
                                        IBond focus)

Helper method to locate two terminal atoms in a container for this extended Cis/Trans element. The atoms are ordered such that the first atom is closer to first carrier.

Parameters:

container - structure representation

Returns:

the terminal atoms (ordered)

create

protected IStereoElement<IBond,IBond> create(IBond focus,
                                             List<IBond> 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

getGroupInfo

public int getGroupInfo()

Access the stereo group information - see class doc.

Specified by:

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

Returns:

the group info

setGroupInfo

public void setGroupInfo(int grp)

Set the stereo group information - see class doc.

Specified by:

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

Parameters:

grp - the group info

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

protected static <T> T[] invapply(T[] src,
                                  int[] perm)
