Marshall Schor commented on UIMA-5662:
--------------------------------------
The CasCompleteSerializer I believe will now store unreachable FSs. I guess
some docs need improving - can you point to where?
> uv3 support CAS deserialization subsequent low level access

> Key: UIMA-5662
> URL: https://issues.apache.org/jira/browse/UIMA-5662
> Project: UIMA
> Issue Type: Improvement
> Components: Core Java Framework
> Affects Versions: 3.0.0SDK-beta
> Reporter: Marshall Schor
> Assignee: Marshall Schor
> Priority: Minor
> Fix For: 3.0.0SDK
>
>
> Some users depend 1) constant v2-ids for FSs preserved in deserialization and
> serialization, and 2) low level cas API access to these.
> V3 normally doesn't maintain tables linking ids to FSs, as these (unless weak
> refs are used) prevent GC of unreachable FSs.
> Based on a mode, set by -Duima.deserialize_perserve_ids, and also
> controllable by new config option per deserialize call, alter the
> deserialization for those deserializers which know about v2 ids, to put these
> into the map used for low-level CAS access, using the actual v2 ids, and
> change the v3 next available id for future new FSs to be 1 beyond the end.
> The -Duima.deserialize-preserve_ids global setting is needed to handle the
> use case of some annotators using low-level APIs, when part of a pipeline is
> "remoted".
