add_json_info()

template<typename Context >

virtual void Parse_tree_node_tmpl< Context >::add_json_info ( Json_object *  json_obj )

inlineprotectedvirtual

Add all the node-specific json fields.

Any class that needs to add such info should override this function rather than doing it in do_contextualize(). E.g. the parse tree node for AVG() may have "distinct" field to indicate if AVG(DISTINCT ...) is used or not.

Parameters

json_obj

Json object for this parse tree node.
