Subject [jira] Commented: (LUCENE-1749) FieldCache introspection API
Date Tue, 04 Aug 2009 19:16:14 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-1749?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12739108#action_12739108
] 

Mark Miller commented on LUCENE-1749:
-------------------------------------

bq. is it a bug that AverageGuessMemoryModel.getSize() will NPE on a non primitive class ...
or should/will the docs for that API say it only works on primitives?

Its only meant to work with primitives. I'll change the name to getPrimitiveSize - on my last
pass through, I'll also review the javadoc for the classes I added.

> FieldCache should expose an Expert level API for runtime introspection of the FieldCache
to provide info about what is in the FieldCache at any given moment.  We should also provide
utility methods for sanity checking that the FieldCache doesn't contain anything "odd"...
>    * entries for the same reader/field with different types/parsers
>    * entries for the same field/type/parser in a reader and it's subreader(s)
>    * etc...
