Class LongElementHandler

java.lang.Object
  net.sf.stax.StAXContentHandlerBase
      net.sf.stax.LongElementHandler

All Implemented Interfaces:

StAXContentHandler

public final class LongElementHandler
extends StAXContentHandlerBase

StAX handler for any element which just contains a string representation of a long. The long value, returned by the endTree(StAXContext) method, is available to a parent handler via its endElement(String, String, String, Object, StAXContext) method.

Ex.

 class MyHandler
     extends StAXContentHandlerBase
 {
     private Long longValue;
     private LongElementHandler longHandler = new LongElementHandler();

     public void startElement(..., StAXDelegationContext dctx)
     {
         // ...
         dctx.delegate(longHandler);
     }

     public void endElement(..., Object result, ...)
     {
         this.longValue = (Long) result;
     }
 }
