        Overrides:
        value in class LeafNode<java.lang.String>
        Returns:
        the string representation of this ReferenceNode.

      • getValue

        public java.lang.String getValue()
        Description copied from class: LeafNode
        Subclasses must implement this, in compliance with the rules given in the return tag.
        Specified by:
        getValue in class LeafNode<java.lang.String>
        Returns:
