Subject [jira] Commented: (LUCENE-2310) Reduce Fieldable, AbstractField and Field complexity
Date Sun, 21 Mar 2010 11:13:27 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-2310?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12847914#action_12847914
] 

Chris Male commented on LUCENE-2310:
------------------------------------

The patch I just attached makes a test in InstantiatedIndex fail because it tries to remove
a field through the iterator.  This illustrates a concern I have with making the iterator
unmodifiable, there is no efficient way to remove a field while iterating, without also running
into a CCE.  I will think over this issue a little bit before deciding whether to continue
with the unmodifiable iterator or not.

> In order to move field type like functionality into its own class, we really need to
try to tackle the hierarchy of Fieldable, AbstractField and Field.  Currently AbstractField
depends on Field, and does not provide much more functionality that storing fields, most of
which are being moved over to FieldType.  Therefore it seems ideal to try to deprecate AbstractField
(and possible Fieldable), moving much of the functionality into Field and FieldType.
