Notation

AI-generated Key Takeaways

• The Notation interface in the Document Object Model (DOM) represents a notation declared in the DTD, used for unparsed entities or processing instruction targets.

• Notation nodes are read-only and do not have a parent node.

• Notation nodes contain a public identifier and a system identifier, accessible via getPublicId() and getSystemId() methods, respectively.

• The nodeName attribute of a Notation node is set to its declared name.

public interface Notation implements Node

This interface represents a notation declared in the DTD. A notation either declares, by name, the format of an unparsed entity (see section 4.7 of the XML 1.0 specification [XML 1.0]), or is used for formal declaration of processing instruction targets (see section 2.6 of the XML 1.0 specification [XML 1.0]). The nodeName attribute inherited from Node is set to the declared name of the notation.

The DOM Core does not support editing Notation nodes; they are therefore readonly.

A Notation node does not have any parent.

Inherited Method Summary

From interface org.w3c.dom.Node

abstract Node	appendChild(Node newChild) Adds the node newChild to the end of the list of children of this node.
abstract Node	cloneNode(boolean deep) Returns a duplicate of this node, i.e., serves as a generic copy constructor for nodes.
abstract short	compareDocumentPosition(Node other) Compares the reference node, i.e.
abstract NamedNodeMap	getAttributes() A NamedNodeMap containing the attributes of this node (if it is an Element) or null otherwise.

abstract String	getNamespaceURI() The namespace URI of this node, or null if it is unspecified (see ).
abstract Node	getNextSibling() The node immediately following this node.
abstract String	getNodeName() The name of this node, depending on its type; see the table above.
abstract short	getNodeType() A code representing the type of the underlying object, as defined above.
abstract String	getNodeValue() The value of this node, depending on its type; see the table above.
abstract Document	getOwnerDocument() The Document object associated with this node.
abstract Node	getParentNode() The parent of this node.
abstract String	getPrefix() The namespace prefix of this node, or null if it is unspecified.
abstract Node	getPreviousSibling() The node immediately preceding this node.
abstract String	getTextContent() This attribute returns the text content of this node and its descendants.
abstract Object	getUserData(String key) Retrieves the object associated to a key on a this node.
abstract boolean	hasAttributes() Returns whether this node (if it is an element) has any attributes.
abstract boolean	hasChildNodes() Returns whether this node has any children.
abstract Node	insertBefore(Node newChild, Node refChild) Inserts the node newChild before the existing child node refChild.
abstract boolean	isDefaultNamespace(String namespaceURI) This method checks if the specified namespaceURI is the default namespace or not.
