42  * A ChainablePropertySet has the following features:
43  *
44  * 1. It implements both the PropertySet and MultiPropertySet interfaces.
45  * 2. It can be 'included' in a MasterPropertySet to seamlessly appear as if
46  *    if it's properties were in the master.
47  *
48  * To be used as a base class for PropertySets, the subclass must implement
49  * the 6 protected pure virtual functions. If a mutex is passed to the
50  * constructor, this is locked before any call to _getSingleValue or
51  * _setSingleValue and released after all processing has completed
52  * (including _postSetValues or _postGetValues )
53  *
54  * The implementations of getPropertyValues/setPropertyValues call
55  * lockMutex and _preGetValues/_preSetValues once before calling
56  * _getSingleValue/_setSingleValue for each property. After each
57  * property has been dealt with, _postGetValues/_postSetValues
58  * are called once.
59  *
60  * Any MasterPropertySet implementations that can include an
61  * implementation of a given ChainablePropertySet must be
62  * declared as a 'friend' in the implementation of the ChainablePropertySet.
