org.exist.dom.NodeProxy
Placeholder class for DOM nodes. NodeProxy is an internal proxy class, acting as a placeholder for all types of persistent XML nodes during query processing. NodeProxy just stores the node's unique id and the document it belongs to. Query processing deals with these proxys most of the time. Using a NodeProxy is much cheaper than loading the actual node from the database. The real DOM node is only loaded, if further information is required for the evaluation of an XPath expression. To obtain the real node for a proxy, simply call {@link #getNode()}. All sets of type NodeSet operate on NodeProxys. A node set is a special type of sequence, so NodeProxy does also implement {@link org.exist.xquery.value.Item} andcan thus be an item in a sequence. Since, according to XPath 2, a single node is also a sequence, NodeProxy does itself extend NodeSet. It thus represents a node set containing just one, single node. @author Wolfgang Meier
