Examples of net.sf.saxon.om.DocumentInfo

net.sf.saxon.om.DocumentInfo
This interface represents a document node as defined in the XPath 2.0 data model. It extends NodeInfo, which is used to represent any node. Every document node must be an instance of DocumentInfo.
The interface supports two methods in addition to those for NodeInfo: one to find elements given their ID value, and one to locate unparsed entities. In addition, document nodes have an important property that is not true of nodes in general: two distinct Java DocumentInfo objects never represent the same document node. So the Java "==" operator returns the same result as the {@link NodeInfo#isSameNodeInfo}method.
This interface is part of the Saxon public API, and as such (from Saxon8.4 onwards) those methods that form part of the stable public API are labelled with a JavaDoc "since" tag to indicate when they were added to the product. @author Michael H. Kay @since 8.4
