    1.32 +/** 
    1.33 +CWsObject is the base class for the server-side objects that are visible to the client.
    1.34 +
    1.35 +The client refers to these objects via a handle that is passed to it by the server.
    1.36 +The association between handles and CWsObject instances is stored by the TWsObject class.
    1.37 +
    1.38 +Derived classes must implement the CommandL() function so that it handles the requests
    1.39 +the client sent.
    1.40 +
    1.41 +Each client session has a list of all its CWsObject instances. When creating an instance of 
    1.42 +a class derived from CWsObject the NewObjL() function must be called to add the new 
    1.43 +object to the list. The CWsObject destructor takes care of removing the object from the list.
