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.

Copy the document fragment starting at the specified node to the given document builder.

Parameters:

node -

receiver -

Throws:

org.xml.sax.SAXException

copyTo

protected void copyTo(NodeImpl node,
                      DocumentBuilderReceiver receiver,

expand

public void expand()

Expand all reference nodes in the current document, i.e. replace them by real nodes. Reference nodes are just pointers to nodes from other documents stored in the database. The XQuery engine uses reference nodes to speed up the creation of temporary doc fragments. This method creates a new copy of the document contents and expands all reference nodes.

Overrides:

                     Receiver receiver)
              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.

Parameters:

serializer -

node -

receiver -

Throws:

org.xml.sax.SAXException
