Class DASEntryPointContentHandler

java.lang.Object
  org.xml.sax.helpers.DefaultHandler
      apollo.dataadapter.das.simple.DASEntryPointContentHandler

All Implemented Interfaces:

org.xml.sax.ContentHandler, org.xml.sax.DTDHandler, org.xml.sax.EntityResolver, org.xml.sax.ErrorHandler

public class DASEntryPointContentHandler
extends org.xml.sax.helpers.DefaultHandler

I am the ContentHandler used when SimpleDASServer parses the result of a 'entry_points' call to a das data source and dsn.

I am DAS 1.0 compliant.

During the parse, I create a list, stored on myself, of the returned entry points. This list is retrieved by calling getSegments after the parse is complete
