Detailed Description

template<class SINGLETON_CLASS>
class SerializableSingleton< SINGLETON_CLASS >

This is a "wrapper" allowing more straightforward serialization of singleton classes. Any singleton class which needs to be serialized should inherit from this base. It provides both part of the "singleton-ness" (by inheriting from boost::noncopyable), and also a method GetSerializationWrapper(). Users of the singleton which wish to serialize it should not do so directly. Instead, they should call GetSerializationWrapper and serialize the returned pointer. Doing so will ensure that only a single global instance of the singleton is maintained when loading from an archive.

Note that if this is not done, and the singleton is serialized directly via the instance pointer, then objects loaded from the archive will refer to a different instance of the singleton from other code!

Usage examples:

For saving:

output_arch << p_wrapper;
SerializableSingleton< SINGLETON_CLASS > * GetSerializationWrapper() const

For loading:

input_arch >> p_wrapper;

Within a serialize method:

archive & p_wrapper;

Note that immediately after a load the wrapper pointer loaded into becomes invalid; call GetSerializationWrapper again if you need a new wrapper for a subsequent save.
