Class CXMLHandlerBase

    java.lang.Object

      +--org.xml.sax.HandlerBase
            |
            +--oracle.xml.parser.v2.DefaultXMLDocumentHandler
                  |
                  +--oracle.xml.comp.CXMLHandlerBase

All Implemented Interfaces:
  ContentHandler, DocumentHandler, DTDHandler, EntityResolver, ErrorHandler, LexicalHandler, XMLDocumentHandler

public class CXMLHandlerBase
extends DefaultXMLDocumentHandler
implements ContentHandler, LexicalHandler

The SAX compression is implemented using SAX Handler which compresses the data based on SAX events. To use the SAX compression, the application needs to implement this interface and register with the SAX parser via `Parser.setDocumentHandler()`
