Instance Method Details

#_as ⇒ Object Also known as: as

The method #as allows you to take an object and use it in a block. If you return a non-nil value, #as will return that value, otherwise the original object is returned.

This is particularly useful with super.

def overridden_method
  super.as |value|
    if value.is_a? String
      Array.wrap(value)
    end
  end
end

Is equivalent to:

def overridden_method
  _overridden_method = super

  if _overridden_method.is_a? String
    Array.wrap(_overridden_method)
  else
    _overridden_method
  end
end
