Class ElementNSImpl

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Cloneable, org.w3c.dom.Element, org.w3c.dom.ElementTraversal, org.w3c.dom.events.EventTarget, org.w3c.dom.Node, org.w3c.dom.NodeList, org.w3c.dom.TypeInfo
    Direct Known Subclasses:
    DeferredElementNSImpl, PSVIElementNSImpl
    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.

    INTERNAL:

    Usage of this class is not supported. It may be altered or removed at any time.

    • Method Detail

      • getNamespaceURI

        public java.lang.String getNamespaceURI()
        Introduced in DOM Level 2.

        The namespace URI of this node, or null if it is unspecified.

        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.

        Specified by:
        getNamespaceURI in interface org.w3c.dom.Node
        Overrides:
        getNamespaceURI in class NodeImpl
        Since:
        WD-DOM-Level-2-19990923
        See Also:
        AttrNSImpl, ElementNSImpl

      • getPrefix

        public java.lang.String getPrefix()
        Introduced in DOM Level 2.

        The namespace prefix of this node, or null if it is unspecified.

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

        Specified by:
        getPrefix in interface org.w3c.dom.Node
        Overrides:
        getPrefix in class NodeImpl
        Since:
        WD-DOM-Level-2-19990923
        See Also:

      • setPrefix

        public void setPrefix​(java.lang.String prefix)
               throws org.w3c.dom.DOMException
        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 interface org.w3c.dom.Node
        Overrides:
        setPrefix in class NodeImpl
        Parameters:
        prefix - The namespace prefix of this node, or null(empty string) if it is unspecified.
        Throws:
        INVALID_CHARACTER_ERR - Raised if the specified prefix contains an invalid character.
        org.w3c.dom.DOMException

      • getLocalName

        public java.lang.String getLocalName()
        Introduced in DOM Level 2.

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

        Specified by:
        getLocalName in interface org.w3c.dom.Node
        Overrides:
        getLocalName in class NodeImpl

      • getXMLBaseAttribute

        protected org.w3c.dom.Attr getXMLBaseAttribute()
        NON-DOM Returns the xml:base attribute.
        Overrides:
        getXMLBaseAttribute in class ElementImpl

      • getTypeName

        public java.lang.String getTypeName()
        Specified by:

                             int derivationMethod)
        Introduced in DOM Level 2.

        Checks if a type is derived from another by restriction. See: http://www.w3.org/TR/DOM-Level-3-Core/core.html#TypeInfo-isDerivedFrom

        Specified by:
        isDerivedFrom in interface org.w3c.dom.TypeInfo
        Overrides:
        isDerivedFrom in class ElementImpl
        Parameters:
