Class InChIGeneratorFactory

java.lang.Object

org.openscience.cdk.inchi.InChIGeneratorFactory

public class InChIGeneratorFactory
extends Object

Factory providing access to InChIGenerator and InChIToStructure. See those classes for examples of use. These methods make use of the JNI-InChI library.

The InChIGeneratorFactory is a singleton class, which means that there exists only one instance of the class. An instance of this class is obtained with:

 InChIGeneratorFactory factory = InChIGeneratorFactory.getInstance();
 

InChI/Structure interconversion is implemented in this way so that we can check whether or not the native code required is available. If the native code cannot be loaded during the first call to getInstance method (when the instance is created) a CDKException will be thrown. The most common problem is that the native code is not in the * the correct location. Java searches the locations in the PATH environmental variable, under Windows, and LD_LIBRARY_PATH under Linux, so the JNI-InChI native libraries must be in one of these locations. If the JNI-InChI jar file is being used and either the current working directory, or '.' are contained in PATH of LD_LIBRARY_PATH then the native code should be placed automatically. If the native files are in the correct location but fail to load, then they may need to be recompiled for your system. See:

Method Detail

getInstance

public static InChIGeneratorFactory getInstance()
                                         throws CDKException

Gives the one InChIGeneratorFactory instance, if needed also creates it.

Returns:

the one InChIGeneratorFactory instance

Throws:

CDKException - if unable to load native code when attempting to create the factory

setIgnoreAromaticBonds

@Deprecated
public void setIgnoreAromaticBonds(boolean ignore)

Deprecated. "the use of aromatic bonds is strongly discouraged" - InChI FAQ, the InChI will fail for many compounds if ignore aromatic bonds is not enabled and the compound have aromatic flags.

Sets whether aromatic bonds should be treated as single and double bonds for the InChI generation. The bond type INCHI_BOND_TYPE.ALTERN is considered special in contrast to single, double, and triple bonds, and is not bulletproof. If the molecule has clearly defined single and double bonds, the option can be used to force the class not to use the alternating bond type. http://www.inchi-trust.org/fileadmin/user_upload/html/inchifaq/inchi-faq.html#16.3

Parameters:

ignore - if aromatic bonds should be treated as bonds of type single and double

getIgnoreAromaticBonds

@Deprecated
public boolean getIgnoreAromaticBonds()

Deprecated.

Returns whether aromatic bonds are treated as single and double bonds for the InChI generation.

Returns:

if aromatic bonds are treated as bonds of type single and double

getInChIGenerator

public InChIGenerator getInChIGenerator(IAtomContainer container)
                                 throws CDKException
