Instance Method Details

#optimizable? ⇒ Boolean

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Test if the operand is an Sorted

Returns:

• (Boolean)

def optimizable?
  operand.kind_of?(Axiom::Relation::Operation::Sorted)
end

#optimize ⇒ Sorted
