All Implemented Interfaces:

ContentHandler, DTDHandler, EntityResolver, ErrorHandler

public class ChainedOfBizSaxHandler
extends DefaultHandler

A base class used for processing a JIRA backup file. This collects Entity information and calls the ImportOfBizEntityHandler.handleEntity(String, java.util.Map) method on its registered delegates. The attributes map includes any attributes that may be nested as sub-elements.
If you construct this with a TaskProgressSink then the progress of the XML processing will be relayed.

Since:

v3.13
