[jira] [Updated] (BEAM-2980) BagState.isEmpty needs a tighter spec
[ https://issues.apache.org/jira/browse/BEAM-2980?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Beam JIRA Bot updated BEAM-2980:
--------------------------------
Priority: P3 (was: P2)
> BagState.isEmpty needs a tighter spec
> -------------------------------------
>
> Key: BEAM-2980
> URL: https://issues.apache.org/jira/browse/BEAM-2980
> Project: Beam
> Issue Type: Bug
> Components: beam-model
> Reporter: Kenneth Knowles
> Priority: P3
> Labels: stale-P2
>
> Consider the following:
> {code}
> BagState<X> myBag = // empty
> ReadableState<Boolean> isMyBagEmpty = myBag.isEmpty();
> myBag.add(bizzle);
> bool empty = isMyBagEmpty.read();
> {code}
> Should {{empty}} be true or false? We need a consistent answer, across all kinds of state, when snapshots are required.
