Subject [jira] [Commented] (OAK-84) Delegates for Session, Node, Property and Item
Date Thu, 03 May 2012 17:20:55 GMT

    [ https://issues.apache.org/jira/browse/OAK-84?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13267600#comment-13267600

Michael Dürig commented on OAK-84:

Ah... in contrast, Item.getSession() says "Return the Session through which this item was

Should we try to get rid of this requirement? It seems overly strict, not consistent (i.e.
different for Workspace and Item) and not clearly speced.

> Instead of passing around Nodes internally and casting them down to NodeImpl we should
use the façade pattern and delegate from NodeImpl back to an implementation class which is
used internally. This also avoids the problem of API clients accessing stuff they shouldn't
by casting to the implementation. 
> Some initial work has been done already. What's left to do it: 
> * Push down as much as possible from ItemImpl, NodeImpl and PropertyImpl to the respective
delegate classes
> * Introduce the same pattern for SessionImpl and do away with SessionContext.
