Does res judicata bar a federal constitutional claim whether it was asserted in a state action?

where the federal constitutional claim is based on the same asserted wrong as was the subject of a state action, and where the parties are the same, res judicata will bar the federal constitutional claim whether it was asserted in state court or not, for the reason that the state judgment on the merits serves not only to bar every claim that was raised in state court but also to preclude the assertion of every legal theory or ground for recovery that might have been raised in support of the granting of the desired relief.
