------------------------------------
Summary: eliminate need for shared data parameter in xmi
serialization
Key: UIMA-4991
URL: https://issues.apache.org/jira/browse/UIMA-4991
Project: UIMA
Issue Type: Improvement
Components: Core Java Framework
Affects Versions: 2.8.1SDK
Reporter: Marshall Schor
Assignee: Marshall Schor
Priority: Minor
Fix For: 3.0.0SDKexp, 2.8.2SDK
The recent problem ( UIMA-4990 ) was caused by an improper use of a mostly
undocumented parameter in the XMI serialization API - the
XmiSerializationSharedData parameter. This is used for handling
out-of-type-system data when sending a CAS to a remote service, and for merging
multiple CASes being returned from multiple remote services.
It is easy to misuse, and can result in strange errors (e.g. UIMA-4990 ).
This improvement would move this to be an internal capability, no longer
exposed in the API (existing API uses with it would be deprecated; instances of
this, if passed in, would be ignored in favor of internal memory for this).
This would enable automatic management of this data. There is a similar concept
in the experimental Uima V3 prototype and an extra CAS Api for eliminating the
extra storage if sophisticated users know early on it won't be needed.
