`abstract Unit`	`reset()`	Force the loading time to expire
`abstract Unit`	`save(UrlAware url, UrlTopic topic)`	Save the url to the external repository
`abstract Unit`	`saveAll(Iterable<UrlAware> urls, UrlTopic topic)`	Save all the url to the external repository
`abstract Boolean`	`hasMore()`	If there are more items in the source
`abstract Boolean`	`hasMore(UrlTopic topic)`	If there are more items with topic in the source
`abstract Integer`	`countRemaining()`	Count remaining size, this operation might be slow for a large url database, use estimateRemaining for fast counting.
`abstract Integer`	`countRemaining(UrlTopic topic)`	Count remaining size with topic, this operation might be slow for a large url database, use estimateRemaining for fast counting.
`abstract Integer`	`estimateRemaining()`	Estimate the size of remaining items, this operation should be very fast
`abstract Integer`	`estimateRemaining(UrlTopic topic)`	Estimate the size of remaining items, this operation should be very fast
`abstract Collection<UrlAware>`	`loadToNow(Collection<UrlAware> sink, Integer size, UrlTopic topic)`	Load items from the source to the sink immediately
`abstract <T extends Any> Collection<T>`	`loadToNow(Collection<T> sink, Integer size, UrlTopic topic, Function1<UrlAware, T> transformer)`	Load items from the source to the sink immediately
`abstract Unit`	`loadTo(Collection<UrlAware> sink, Integer size, UrlTopic topic)`	Load items from the source to the sink safely
`abstract <T extends Any> Unit`	`loadTo(Collection<T> sink, Integer size, UrlTopic topic, Function1<UrlAware, T> transformer)`	Load items from the source to the sink safely
`abstract Long`	`deleteAll(UrlTopic topic)`	Delete all items with topic from the source
