@Deprecated @PublicApi public class StereoisomerPlugin extends CalculatorPlugin
Deprecated.
Plugin class for stereoisomer calculation. * Data types:
  • "structure"
  • "structures"
  • "count"

API usage example: 

 // read input molecule
 MolImporter mi = new MolImporter("test.mol");
 Molecule mol = mi.read();
 mi.close();

 // create plugin
 StereoisomerPlugin plugin = new StereoisomerPlugin();

 // set target molecule
 plugin.setMolecule(mol);

 // set parameters for calculation
 plugin.setStereoisomerismType(StereoisomerPlugin.TETRAHEDRAL);

 // run the calculation
 plugin.run();

 // get results
 Molecule[] stereoisomers = plugin.getStereoisomers();
 int stereoisomerCount = plugin.getStereoisomerCount();
 for (Molecule m : stereoisomers) { // or:  m = plugin.getStereoisomer(i);
     // do something with molecule ...
 }

 // do something with the results ...

Note: Stereoisomer plugin does not handle enhanced stereo information. Enhanced stereo information is cleared before generating the stereoisomers.
