Detailed Description

       Self managed single linked list object chain.

       This is used for accumulating lists by using as a base class for a derived subclass.

Member Function Documentation

   virtual LinkedSingle* ost::LinkedSingle::getFirst (void) [virtual]
       Get first linked object in list. This may be dynamically recast, and may refer to a master
       static bookmark pointer in a derived class. Otherwise it simply returns the current
       object. In a 'free' list, this may not only return the first object, but also set the
       first to next.

       Returns
           pointer to first object in list.

   virtual LinkedSingle* ost::LinkedSingle::getLast (void) [virtual]
       Gets the last object in the list. This normally follows the links to the end. This is a
       virtual because derived class may include a static member bookmark for the current end.

       Returns
           pointer to last object in list.

   LinkedSingle* ost::LinkedSingle::getNext (void) [inline]
       Get next object, for convenience. Derived class may use this with a dynamic cast.

       Returns
           next object in list.

   virtual void ost::LinkedSingle::insert (LinkedSingle & obj) [virtual]
       Insert object into chain. This is a virtual because derived class may choose instead to
       perform an insert at head or tail, may manage bookmarks, and may add mutex lock.

       Parameters
           object being inserted.

   LinkedSingle& ost::LinkedSingle::operator+= (LinkedSingle & obj)
