Class ImportContentHandler

java.lang.Object
  org.apache.jackrabbit.rmi.xml.ImportContentHandler

All Implemented Interfaces:

ContentHandler

Direct Known Subclasses:

SessionImportContentHandler, WorkspaceImportContentHandler

public abstract class ImportContentHandler
extends Object
implements ContentHandler

Base class for a SAX content handler for importing XML data. This class provides a general mechanism for converting a SAX event stream to raw XML data and feeding the received byte array into an import method. Subclasses can provide different import mechanisms simply by implementing the abstract importXML(byte[]) method.

ImportContentHandler

public ImportContentHandler()

Creates a SAX content handler for importing XML data.

Method Detail

importXML

protected abstract void importXML(byte[] xml)
                           throws Exception

Imports the given XML data. This method is called by the endDocument() method after the received XML stream has been serialized.

Subclasses must implement this method to provide the actual import mechanism.

Parameters:

xml - the XML data to import

Throws:

Exception - on import errors
