// CLASS DECLARATION

/**

* CSenServiceManager class offers API for accessing and managing 

* WebServicesFramework (WSF) service and identity related data.

* The class is designed using abstract factory pattern: 

* it only offers a instance (pointer) to the actual implementation 

* class meeting this interface.

* Typically, service consumers use of CSenServiceManager to register service

* or identity based data, which is required for accessing some invocable, 

* possibly remote service.

* The class is meant for both default frameworks offered by WSF 

* and for any custom plug-in service invocation framework implementation.

* The default frameworks are:

*      1) Identity Based Web Services Framework (ID-WSF).

*      2) Basic Web Services Framework.

* For Basic Web Service consumer, the only applicable operations are 

* Identity data managing methods. These can be used to make connection 

* specific Basic Authentication (BASIC-AUTH) credentials available without 

* later end-user interaction. Otherwise required authentication info 

* will be requested via notifier dialog prompts.

* ID-WSF consumer has to use the CSenServiceManager methods to register 

* authentication service description and identity provider (which are 

* the same service in ID-WSF) and finally associate some actual service 

* (contract to a WSP) to this IDP.

* 

* The current client-server framework implementation of CSenServiceManager 

* is synchronous, although class inherits CActive for future extensions.

* So, the class instance will not be an active object handled 

* by ActiveScheduler, and it does not have implementation 

* in RunL() or DoCancel() methods.

*

*  @lib SenServMgr.lib

*  @since Series60 3.0
