Class StereoisomerEnumeration

java.lang.Object
chemaxon.common.util.AbstractIterator<Molecule>
com.chemaxon.calculations.stereoisomers.StereoisomerEnumeration
All Implemented Interfaces:
Iterator<Molecule>
@PublicApi public class StereoisomerEnumeration extends chemaxon.common.util.AbstractIterator<Molecule>
Enumerates stereoisomers of the specified molecule. Iterate over all tetrahedral and cis-trans stereocenters.

API usage example: 

   // construct new calculation with default settings
   StereoisomerEnumeration enumeration =
       new StereoisomerEnumeration(inputMolecule, StereoisomerSettings.create());

   while (enumeration.hasNext()) {            // iterate over all stereoisomers
      Molecule isomer = enumeration.next();   // calculate the next isomer
      ...                                     // do something with molecule
   }
