Passes consumed items on in a canonical order.
void canonicalizeIdeal(Ideal &ideal)
virtual void consume(const Term &term)
Consume a term.
virtual void beginConsumingList()
This method is not required to be called.
TermTranslator * _translator
virtual void doneConsuming()
Must be called once after each time beginConsuming has been called.
virtual void beginConsuming()
Tell the consumer to begin consuming an ideal.

Passes on the call immediately.
