Subject [jira] Updated: (DERBY-2050) Manipulating CachedItems could be more efficient
Date Wed, 08 Nov 2006 16:10:51 GMT
     [ http://issues.apache.org/jira/browse/DERBY-2050?page=all ]

Dyre Tjeldvoll updated DERBY-2050:

    Attachment: derby-2050.v2.diff

New patch which 
- restores the deleted comment
- removes unintended white space changes
- restores the deleted final keywords

Deletion was not intentional. I wanted to remove the final keywords that I had added myself,
and did not notice that I removed some of the existing ones. I decided to remove the final
keywords I which I had added since I noticed that the class itself was declared final. Is
there some added benefit to declaring methods in a final class as final?

> CachedItem's state is currently recorded in bit fields of an integer variable. Changing
this to 6 boolean member variables reduces cpu usage.
