QAbstractSecuritySession class constructor description is like this.

"Constructs an abstract item model with the given parent."

Note that using this function implies that service and client share the – implamentation-- of T which means that service and client become tightly coupled.

change implamentation to implementation. this is occuring in the following member function also.
