def display_name
  @display_name
end

#execution_stats ⇒ Hash<String,Object>

The execution statistics associated with the node, contained in a group of key- value pairs. Only present if the plan was returned as a result of a profile query. For example, number of executions, number of rows/time per execution etc. Corresponds to the JSON property executionStats

Returns:

  • (Hash<String,Object>)

end

#kind ⇒ String

Used to determine the type of node. May be needed for visualizing different kinds of nodes differently.
