From: Archana Singh <archus(a)linux.vnet.ibm.com&gt; Incase of GET lookup was called twice.Once lookup() before is_authorized() and then in self.get(). This added overhead to system when lookup() is called for each value in list from get_list() of Collection. So to avoid this overhead, lookup() should not be called before self.get(). And hence it make sense to call lookup() from get(), update(), delete() separately. And as is_authorized() used self.info, which is currently being intialized in exception section of lookup(). It make more sense to intialize it in __init__.
