org.apache.jackrabbit.core.xml
Class ImportHandler

java.lang.Object
  org.xml.sax.helpers.DefaultHandler
      org.apache.jackrabbit.core.xml.ImportHandler

All Implemented Interfaces:

ContentHandler, DTDHandler, EntityResolver, ErrorHandler

public class ImportHandler

extends DefaultHandler

An ImportHandler instance can be used to import serialized data in System View XML or Document View XML. Processing of the XML is handled by specialized ContentHandlers (i.e. SysViewImportHandler and DocViewImportHandler).

The actual task of importing though is delegated to the implementation of the Importer interface.

Important Note:

These SAX Event Handlers expect that Namespace URI's and local names are reported in the start/endElement events and that start/endPrefixMapping events are reported (i.e. default SAX2 Namespace processing).
