org.xmlcml.simplecml
Class CMLEventHandler  

java.lang.Object
  org.xmlcml.simplecml.CMLEventHandler

All Implemented Interfaces:

com.microstar.xml.XmlHandler

---

public class CMLEventHandler

extends java.lang.Object

implements com.microstar.xml.XmlHandler

SAX-like CML reader, hacked from David Megginson's AElfred demo; although this is deprecated, it is used to provide 1.02 compatibility also it is unlikely that its problems will be relevant in chemistry.

Methods in this class are not called directly, but by Aelfred. Typical usage:

        try {
      CMLEventHandler evh = new CMLEventHandler();
      evh.doParse(fileName);
      SimpleMolecule mol = evh.topMolecule;
    } catch (Exception e) {
        e.printStackTrace();
        System.out.println("Failed to read file: "+e);
    }
 

mol can then be used as a SimpleMolecule
