Class InChIToStructure

java.lang.Object

org.openscience.cdk.inchi.InChIToStructure

public class InChIToStructure
extends Object

This class generates a CDK IAtomContainer from an InChI string. It places calls to a JNI wrapper for the InChI C++ library.

The generated IAtomContainer will have all 2D and 3D coordinates set to 0.0, but may have atom parities set. Double bond and allene stereochemistry are not currently recorded.
Example usage // Generate factory - throws CDKException if native code does not load
InChIGeneratorFactory factory = new InChIGeneratorFactory();
// Get InChIToStructure
InChIToStructure intostruct = factory.getInChIToStructure(
inchi, DefaultChemObjectBuilder.getInstance()
);

INCHI_RET ret = intostruct.getReturnStatus();
if (ret == INCHI_RET.WARNING) {
// Structure generated, but with warning message
System.out.println("InChI warning: " + intostruct.getMessage());
} else if (ret != INCHI_RET.OKAY) {
// Structure generation failed
throw new CDKException("Structure generation failed failed: " + ret.toString()
+ " [" + intostruct.getMessage() + "]");
}

IAtomContainer container = intostruct.getAtomContainer();
