Class ElementNSImpl

  • All Implemented Interfaces:
    Cloneable, Element, EventTarget, Node, NodeList, TypeInfo
    public class ElementNSImpl
extends ElementImpl
    ElementNSImpl inherits from ElementImpl and adds namespace support.

    The qualified name is the node name, and we store localName which is also used in all queries. On the other hand we recompute the prefix when necessary.

    • Field Detail

      • namespaceURI

        protected String namespaceURI
        DOM2: Namespace URI.

      • localName

        protected String localName
        DOM2: localName.

    • Method Detail

      • getNamespaceURI

        public String getNamespaceURI()
        Introduced in DOM Level 2.

        The namespace URI of this node, or null if it is unspecified. When this node is of any type other than ELEMENT_NODE and ATTRIBUTE_NODE, this is always null and setting it has no effect.

        This is not a computed value that is the result of a namespace lookup based on an examination of the namespace declarations in scope. It is merely the namespace URI given at creation time.

        For nodes created with a DOM Level 1 method, such as createElement from the Document interface, this is null. Introduced in DOM Level 2.

      • getPrefix

        public String getPrefix()
        Introduced in DOM Level 2.

        The namespace prefix of this node, or null if it is unspecified. When this node is of any type other than ELEMENT_NODE and ATTRIBUTE_NODE this is always null and setting it has no effect.

        For nodes created with a DOM Level 1 method, such as createElement from the Document interface, this is null. Introduced in DOM Level 2.

      • setPrefix

        public void setPrefix​(String prefix)
               throws DOMException
        Introduced in DOM Level 2.

        The namespace prefix of this node, or null if it is unspecified. When this node is of any type other than ELEMENT_NODE and ATTRIBUTE_NODE this is always null and setting it has no effect.

        For nodes created with a DOM Level 1 method, such as createElement from the Document interface, this is null.

        Note that setting this attribute changes the nodeName attribute, which holds the qualified name, as well as the tagName and name attributes of the Element and Attr interfaces, when applicable. Introduced in DOM Level 2.

        Note that setting this attribute changes the nodeName attribute, which holds the qualified name, as well as the tagName and name attributes of the Element and Attr interfaces, when applicable.

        Specified by:

        setPrefix in class NodeImpl
        Parameters:
        prefix - The namespace prefix of this node, or null(empty string) if it is unspecified.
        Throws:
        DOMException - INVALID_CHARACTER_ERR Raised if the specified prefix contains an invalid character.

      • getLocalName

        public String getLocalName()
        Introduced in DOM Level 2.

        Returns the local part of the qualified name of this node. For nodes created with a DOM Level 1 method, such as createElement from the Document interface, and for nodes of any type other than ELEMENT_NODE and ATTRIBUTE_NODE this is the same as the nodeName attribute. Introduced in DOM Level 2.

        Returns the local part of the qualified name of this node.

        Introduced in DOM Level 3.
