                                      boolean includeAncestors)
        Output all namespace nodes associated with this element. Does nothing if the node is not an element.
        Specified by:
        sendNamespaceDeclarations in interface NodeInfo
        Parameters:
        out - The relevant outputter
        includeAncestors - True if namespaces declared on ancestor

      • getDeclaredNamespaces

        public int[] getDeclaredNamespaces​(int[] buffer)
        Get all namespace undeclarations and undeclarations defined on this element.
        Specified by:
        getDeclaredNamespaces in interface NodeInfo
        Parameters:
        buffer - If this is non-null, and the result array fits in this buffer, then the result may overwrite the contents of this array, to avoid the cost of allocating a new array on the heap.
        Returns:
        An array of integers representing the namespace declarations and undeclarations present on this element. For a node other than an element, return null. Otherwise, the returned array is a sequence of namespace codes, whose meaning may be interpreted by reference to the name pool. The top half word of each namespace code represents the prefix, the bottom half represents the URI. If the bottom half is zero, then this is a namespace undeclaration rather than a declaration. The XML namespace is never included in the list. If the supplied array is larger than required, then the first unused entry will be set to -1.

        For a node other than an element, the method returns null.

        Returns:
        the typed value of the item. In general this will be a sequence

      • atomize

        public Value atomize()
        Get the typed value. The result of this method will always be consistent with the method Item.getTypedValue(). However, this method is often more convenient and may be more efficient, especially in the common case where the value is expected to be a singleton.
        Specified by:
        atomize in interface NodeInfo
        Returns:
        the typed value. If requireSingleton is set to true, the result will always be an AtomicValue. In other cases it may be a Value representing a sequence whose items are atomic values.
        Since:
        8.5

      • getPublicId

        public java.lang.String getPublicId()
        Return the public identifier for the current document event.

        Specified by:
        getPublicId in interface javax.xml.transform.SourceLocator
        Returns:
        A string containing the public identifier, or null if none is available.

      • getColumnNumber

        public int getColumnNumber()
        Return the character position where the current document event ends.

        Warning: The return value from the method is intended only as an approximation for the sake of error reporting; it is not intended to provide sufficient information to edit the character content of the original XML document.

        The return value is an approximation of the column number in the document entity or external parsed entity where the markup that triggered the event appears.

        Specified by:
        getColumnNumber in interface javax.xml.transform.SourceLocator
        Returns:
        The column number, or -1 if none is available.
