#intermediate_variables(*sub_flows) ⇒ Object

Output variables which are not directly referenced by this flow, but which are referenced by a parent flow and set by the given child flow and therefore must pass through the current flow. By calling this method with no argument it will consider variables set by any child flow, alternatively pass in the variables for the child flow in question and only that will be considered.
