        Set the namespace declarations for the element
      • getURICodeForPrefix

        public short getURICodeForPrefix​(java.lang.String prefix)
                                  throws NamespaceException
        Search the NamespaceList for a given prefix, returning the corresponding URI.
        Overrides:
        getURICodeForPrefix in class ElementImpl
        Parameters:
        prefix - The prefix to be matched. To find the default namespace, supply ""
        Returns:
        The URI code corresponding to this namespace. If it is an unnamed default namespace, return Namespace.NULL_CODE.
        Throws:
        NamespaceException - if the prefix has not been declared on this NamespaceList.
      • getPrefixForURI

        public java.lang.String getPrefixForURI​(java.lang.String uri)
        Search the NamespaceList for a given URI, returning the corresponding prefix.
        Overrides:
        getPrefixForURI in class ElementImpl
        Parameters:
        uri - The URI to be matched.
        Returns:
        The prefix corresponding to this URI. If not found, return null. If there is more than one prefix matching the URI, the first one found is returned. If the URI matches the default namespace, return an empty string.
      • addNamespaceNodes

        public void addNamespaceNodes​(ElementImpl owner,
                                      java.util.Vector list,

        Make the set of all namespace nodes associated with this element.
        Overrides:
        addNamespaceNodes in class ElementImpl
        Parameters:
        owner - The element owning these namespace nodes.
        list - a Vector containing NamespaceImpl objects representing the namespaces in scope for this element; the method appends nodes to this Vector, which should initially be empty. Note that the returned list will never contain the XML namespace (to get this, the NamespaceEnumeration class adds it itself). The list WILL include an entry for the undeclaration xmlns=""; again it is the job of NamespaceEnumeration to ignore this, since it doesn't represent a true namespace node.
        addXML - Add a namespace node for the XML namespace

        Overrides:
        setAttribute in class ElementImpl
