## org.exist.memtree
Class DocumentImpl

    java.lang.Object
      org.exist.memtree.NodeImpl
          org.exist.memtree.DocumentImpl

All Implemented Interfaces:
  java.lang.Comparable, org.w3c.dom.Document, Item, org.w3c.dom.Node, NodeValue, QNameable, Sequence

public class DocumentImpl
extends NodeImpl
implements org.w3c.dom.Document

An in-memory implementation of Document. This implementation stores all node data in the document object. Nodes from another document, i.e. a persistent document in the database, can be stored as reference nodes, i.e. the nodes are not copied into this document object. Instead a reference is inserted which will only be expanded during serialization.

    `org.w3c.dom.DOMException`

                  throws org.xml.sax.SAXException

  Stream the specified document fragment to a receiver. This method is called by the serializer to output in-memory nodes.
