com.memoire.mst
Class MstHandlerBase  

java.lang.Object
  com.memoire.mst.MstHandlerBase

All Implemented Interfaces:

MstXmlHandler

---

public class MstHandlerBase

extends java.lang.Object

implements MstXmlHandler

Convenience base class for AElfred handlers.

This base class implements the MstXmlHandler interface with (mostly empty) default handlers. You are not required to use this, but if you need to handle only a few events, you might find it convenient to extend this class rather than implementing the entire interface. This example overrides only the charData method, using the defaults for the others:

 

 public class MyHandler extends MstHandlerBase {
   public void charData (char ch[], int start, int length)
   {
     System.out.println("Data: " + new String (ch, start, length));
   }
 }
 

This class is optional, but if you use it, you must also include the MstXmlException class.

Do not extend this if you are using SAX; extend org.xml.sax.MstHandlerBase instead.

Version:

1.1
