Subject [jira] [Commented] (SANDBOX-401) [BeanUtils2] Performance improvement: store hash code of AccessibleObjectDescriptor as member variable
Date Mon, 05 Mar 2012 12:53:57 GMT

    [ https://issues.apache.org/jira/browse/SANDBOX-401?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13222308#comment-13222308

Benedikt Ritter commented on SANDBOX-401:
-----------------------------------------

Okay, I've corrected my configuration. Can you correct the imports, when you apply the patch
or do you want me to create a new one?

TIA!

> As discussed on the ML, we should store the hash code of AccessibleObjectDescriptor in
a private member variable after it has been computed the first time. The computed value can
be returned on subsequent invocations. Since AccessibleObjectDescriptor is immutable (all
of its fields are final) the hash code can never change, once an AccessibleObjectDescriptor
has been initialized.
