CursorSourceBase

A source for a large or unknown-length set you fetch one page at a time (SQL LIMIT/OFFSET, a paged API). The fetcher receives the page index and the page size and reports whether a next page exists. A cursor source has no cheap total, so totalPages is undefined, the last button is omitted, and the indicator reads "Page X".

class CursorSourceBase<Item, Ctx> implements PageSourceBase<Item, Ctx>
