New Revision: 1366328

URL: http://svn.apache.org/viewvc?rev=1366328&view=rev
Log:
Extended the CllerezzaBackend with protected getter and setter for the wrapped Graph. This is intended to allow components that get its Clerezza graph only during activation to extend this LDPath Backend implementations. This will be used by the ClerezzaStore implementation (part of STANBOL-704) to provide also a LDPath Backend.
