Subject [jira] [Commented] (OFBIZ-3774) Add The Visitor Pattern To Screen Widget Model Classes
Date Tue, 15 Nov 2011 14:49:52 GMT

    [ https://issues.apache.org/jira/browse/OFBIZ-3774?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13150529#comment-13150529
] 

Adrian Crum commented on OFBIZ-3774:
------------------------------------

Once all of the behavior has been moved to external classes, we could continue the process
(in a separate Jira issue) to turn the screen widget models into immutable data structures.
That will improve performance and memory use, and it can help cut down on the instances of
thread-unsafe code being introduced into the project (a recurring problem in this project).
