org.rhq.core.domain.drift.DriftDefinition
This is a convienence wrapper around a Configuration object whose schema is that of {@link DriftConfigurationDefinition}. Note that this is not an actual Configuration object - it's got a HAS-A relationship with Configuration. This object also has an optional relationship with a Resource. @author John Sanda @author John Mazzitelli @author Jay Shaughnessy
