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
Collection.store(org.exist.storage.txn.Txn, org.exist.storage.DBBroker, org.exist.collections.IndexInfo, org.xml.sax.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.
