Member Function Documentation

◆ add_json_info()

void PT_limit_clause::add_json_info ( Json_object json_obj)
inlineoverrideprotectedvirtual

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_objJson object for this parse tree node.

Reimplemented from Parse_tree_node_tmpl< Context >.
