    • Method Detail

      • getSequenceNumber

        protected final long getSequenceNumber()
        Get the node sequence number (in document order). Sequence numbers are monotonic but not consecutive. In the current implementation, parent nodes (elements and roots) have a zero least-significant word, while namespaces, attributes, text nodes, comments, and PIs have the top word the same as their owner and the bottom half reflecting their relative position.
        Overrides:
        getSequenceNumber in class NodeImpl
      • hasChildNodes

        public final boolean hasChildNodes()
        Determine if the node has any children.
        Specified by:
        hasChildNodes in interface NodeInfo
        Overrides:
        hasChildNodes in class NodeImpl
        Returns:
        true if the node has any children, false if the node has no children.
      • enumerateChildren

        public final AxisIterator enumerateChildren​(NodeTest test)
        Get an enumeration of the children of this node
        Parameters:
        test - A NodeTest to be satisfied by the child nodes, or null if all child node are to be returned
      • getFirstChild

        public final NodeInfo getFirstChild()
        Get the first child node of the element
        Overrides:
        getFirstChild in class NodeImpl
        Returns:
        the first child node of the required type, or null if there are no children
      • getLastChild

        public final NodeInfo getLastChild()
        Get the last child node of the element
        Overrides:
        getLastChild in class NodeImpl
        Returns:
        the last child of the element, or null if there are no children
      • getNthChild

        protected final NodeImpl getNthChild​(int n)
        Get the nth child node of the element (numbering from 0)
        Returns:
        the last child of the element, or null if there is no n'th child
      • getStringValue

        public java.lang.String getStringValue()
        Return the string-value of the node, that is, the concatenation of the character content of all descendent elements and text nodes.
        Returns:
        the accumulated character content of the element, including descendant elements.

      • useChildrenArray

        public void useChildrenArray​(NodeImpl[] array)
        Supply an array to be used for the array of children. For system use only.
      • addChild

        public void addChild​(NodeImpl node,
                             int index)
        Add a child node to this node. For system use only. Note: normalizing adjacent text nodes is the responsibility of the caller.
      • compact

        public void compact​(int size)
        Compact the space used by this node
