Class XMLIsotopeFactory

java.lang.Object

org.openscience.cdk.config.IsotopeFactory

org.openscience.cdk.config.XMLIsotopeFactory

public class XMLIsotopeFactory
extends IsotopeFactory

Used to store and return data of a particular isotope. As this class is a singleton class, one gets an instance with:

 IsotopeFactory ifac = IsotopFactory.getInstance(new IChemObject().getNewBuilder());
 

Data about the isotopes are read from the file org.openscience.cdk.config.isotopes.xml in the cdk-standard module. Part of the data in this file was collected from the website webelements.org.

The use of this class is exemplified as follows. To get information about the major isotope of hydrogen, one can use this code:

   IsotopeFactory factory = XMLIsotopeFactory.getInstance(DefaultChemObjectBuilder.getInstance());
   Isotope major = factory.getMajorIsotope("H");
