Member Function Documentation

add_cross_join()

PT_joined_table * PT_joined_table::add_cross_join ( PT_cross_join *  cj )

inlineoverridevirtual

Adds the cross join to this join operation.

The cross join is nested as the table reference on the left-hand side.

Reimplemented from PT_table_reference.

add_json_info()

void PT_joined_table::add_json_info ( Json_object *  json_obj )

overrideprotectedvirtual

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.

Reimplemented from Parse_tree_node_tmpl< Context >.

Reimplemented in PT_joined_table_using.

add_rhs()

void PT_joined_table::add_rhs ( PT_table_reference *  table )

inline

Adds the table reference as the right-hand side of this join.

contextualize_tabs()

bool PT_joined_table::contextualize_tabs ( Parse_context *  pc )

protected

do_contextualize()

bool PT_joined_table::do_contextualize ( Parse_context *  pc )
