public
boolean
hasPendingWrites
()
Returns |
boolean |
true if the snapshot contains the result of local writes (e.g. set() or update() calls)
that have not yet been committed to the backend. If your listener has opted into metadata
updates (via `DocumentListenOptions` or `QueryListenOptions`) you will receive another
snapshot with `hasPendingWrites()` equal to false once the writes have been committed to
the backend.
|
public
boolean
isFromCache
()
Returns |
boolean |
true if the snapshot was created from cached data rather than guaranteed up-to-date
server data. If your listener has opted into metadata updates (via `DocumentListenOptions`
or `QueryListenOptions`) you will receive another snapshot with `isFomCache()` equal to
false once the client has received up-to-date data from the backend.
