Subject [jira] [Commented] (JCLOUDS-85) Avoid creating uneeded instance of PropertyShellTableFactory
Date Tue, 02 Jul 2013 17:59:19 GMT

    [ https://issues.apache.org/jira/browse/JCLOUDS-85?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13698041#comment-13698041

Andrew Phillips commented on JCLOUDS-85:
----------------------------------------

> only if no injection takes place

When does the injection take place? I.e. is there a way to determine whether we need to instantiate
the class *without* having to check in every "execute" call, as the current PR does?

>          Issue Type: Improvement
>          Components: jclouds-karaf

> The story here is that we have 2 versions of the ShellTableFactory:
> i) OSGi aware
> ii) Property based
> Our commands always instantiate (ii) and may replace it with (i) when running inside
OSGi.
> We should make sure that we instantiate (ii) only if no injection takes place (e.g. outside
OSGi)
> This could be as simple as checking if the factory is null inside the doExecute method
and then instantiating (ii).
