Instance Method Details

#add_conjunction ⇒ Object

Add a conjunction to the disjunction. This overrides the method in the Scope class since scopes are implicitly conjunctive and thus can return themselves as a conjunction. Inside a disjunction, however, a conjunction must explicitly be created.

  conjunction
end
