## 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)
