Class DOMIndexer

java.lang.Object
  org.exist.memtree.DOMIndexer

public class DOMIndexer

extends java.lang.Object

Helper class to make a in-memory document fragment persistent. The class directly accesses the in-memory document structure and writes it into a temporary doc on the database. This is much faster than first serializing the document tree to SAX and passing it to org.exist.collections.Collection#store(DBBroker, IndexInfo, InputSource, boolean). As the in-memory document fragment may not be a well-formed XML doc (having more than one root element), a wrapper element is put around the content nodes.
