checkOwner
public abstract boolean checkOwner(java.lang.String authorizationId)
throws StandardException

- Specified by:
getObjectID
in interface Dependable
- Returns:
- The provider's UUID
isPersistent
public boolean isPersistent()
- Is this provider persistent? A stored dependency will be required
