[Building Sakai] Web Services for Site removal.

Tue Oct 21 05:39:28 PDT 2014

Hard delete is not in Sakai 10, it is a new feature for Sakai 11 only. You
can backport it though.
The javadocs on the interface say it's since 10.0 but it's actually 11.

https://jira.sakaiproject.org/browse/KNL-1252

It's currently hooked up to Resources so that content is purged if you hard
delete a site. This means that files on the filesystem and binary in the
database is deleted.

Other tools generally just store data in the database. To get those to
delete that data, implement the interface (see the javadocs on the
interface), then the tool will be called upon at delete time to do what it
needs to do to remove its content.
