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.

def optimizable?
  right = self.right
  operation.kind_of?(right.class) && left.eql?(right.left)
end

#optimize ⇒ Function
