Subject [jira] [Updated] (UIMA-4677) UV3 Internal support for Feature Structure IDs
Date Mon, 05 Dec 2016 22:51:58 GMT

     [ https://issues.apache.org/jira/browse/UIMA-4677?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Marshall Schor updated UIMA-4677:
---------------------------------
    Description: 
Feature Structures have IDs; these show up in externalized formats.  In v2, these were the
int heap address. In V3, these are incrementing ints, starting at 1.

Support is needed for PEARs and for low-level createFS methods to hold onto FSs to prevent
them from being garbage collected.  This is provided using a map from IDs to the FS.

Feature Structures have IDs; these show up in externalized formats.  In v2, these were the
int heap address. In V3, -these are incrementing ints, starting at 1.- these are designed
to mimic v2, for backwards compatibility (and to support use-cases that rely on IDs as proxies
for actual references to FS objects).

Support is needed for PEARs and for low-level createFS methods to hold onto FSs to prevent
them from being garbage collected.  This is provided using a map from IDs to the FS.
