Class AbstractNode

Implemented Interfaces:
DOMLocator, Node, NodeInfo, Source, SourceLocator
Known Direct Subclasses:
NodeImpl

public abstract class AbstractNode
extends java.lang.Object
implements Node, NodeInfo, SourceLocator, DOMLocator

This class is an abstract implementation of the Saxon NodeInfo interface; it also contains concrete implementations of most of the DOM methods in terms of the NodeInfo methods. These include all the methods defined on the DOM Node class itself, and most of those defined on subclasses such as Document, Text, and Comment: because of the absence of multiple inheritance, this is the only way of making these methods reusable by multiple implementations. The class contains no data, and can be used as a common superclass for different implementations of Node and NodeInfo.

public boolean isSupported(String feature,
                           String version)
Tests whether the DOM implementation implements a specific feature and that feature is supported by this node.

Parameters:
feature - The name of the feature to test. This is the same name which can be passed to the method hasFeature on DOMImplementation .
version - This is the version number of the feature to test. In Level 2, version 1, this is the string "2.0". If the version is not specified, supporting any version of the feature will cause the method to return true .

Returns:
Returns true if the specified feature is supported on this node, false otherwise.

Since:
DOM Level 2


normalize

public void normalize()
Puts all Text nodes in the full depth of the sub-tree underneath this Node, including attribute nodes, into a "normal" form where only structure (e.g., elements, comments, processing instructions, CDATA sections, and entity references) separates Text nodes, i.e., there are neither adjacent Text nodes nor empty Text nodes.

Since:
DOM Level 2

Output all namespace nodes associated with this element. Does nothing if the node is not an element.
Specified by:
outputNamespaceNodes in interface NodeInfo

Parameters:
out - The relevant outputter
includeAncestors - True if namespaces declared on ancestor elements must be output; false if it is known that these are already on the result tree
