CoreContainer Usage

[Amit Nithian]

I am trying to understand the multicore setup of Solr more and saw
that SolrCore.getCore is deprecated in favor of
CoreContainer.getCore(name). How can I get a reference to the
CoreContainer for I assume it's been created somewhere in Solr and is
it possible for one core to get access to another SolrCore via the
CoreContainer?

Thanks
Amit
