      • setAccessor

        void setAccessor​(ExpressionAccessor accessor)
        Sets a new compiled accessor for this node expression.
        Parameters:
        accessor - The compiled representation of this node.
      • accept

        <R,​P> R accept​(NodeVisitor<? extends R,​? super P> visitor,
                             P data)
                      throws OgnlException

        P - The type of the second parameter type.
        Parameters:
        visitor - The visitor to accept.
        data - The second parameter to pass through to visitor.visit
