Detailed Description

This singleton class allows serialization of a number of objects into (disp) and from (cast) std i/o streams.

The transformation is done at run-time, i.e. SignalCaster doesn't know about the type of objects it casts to.

It also allows registering of user-defined casts. A cast is identified by the compiler. The mapping from a type to a serialization function is dynamic, hence it is more complex than a typical template-based compile-time resolve. So disp, cast and trace are costly functions and should be used as such.

displayer_type

typedef boost::function2<void, const boost::any &, std::ostream &> displayer_type

Typedef of displayer functions that take an encapsulated 'any' object and displays, cast, or trace it on an output stream (serialization).
