Detailed Description

template<typename T>
class alps::alea::internal::format_registry< T >

Allows the addition of custom formatting state to I/O stream objects.

This class allows to store one instance of type T with each std::ios_base instance via the get() method. This in turn can be used to implement user-defined I/O manipulators that modify these format flags and are then used by stream operations with user-defined objects.
