Subject [jira] Updated: (PIVOT-464) Add a BeanMap (or BeanAdapter) class
Date Tue, 20 Apr 2010 14:40:51 GMT

     [ https://issues.apache.org/jira/browse/PIVOT-464?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Greg Brown updated PIVOT-464:
-----------------------------


As a first iteration, BeanAdapter could extend BeanDictionary, and the platform code could
be updated to use BeanAdapter instead. BeanDictionary would then be deprecated and dropped
in a future release.

> This class will extend (or replace) BeanDictionary. It may be called BeanAdapter. It
will be used wherever BeanDictionary is currently used, and will also be used in JSONSerializer#writeObject()
to allow a caller to write arbitrary bean graphs to JSON. 
> The existing BeanDictionaryListener interface will be eliminated as part of this change,
and the functionality for listening to native events will be moved elsewhere (e.g. ComponentPropertyInspectorSkin).
While valuable, the current implementation isn't consistent with how other similar adapter
classes work, since change events are fired even when bean properties change "behind the scenes"
- not just when they are modified via the adapter interface. The potential for memory leaks
due to the current implementation is also undesirable.
