Detailed Description

template<typename StoredType>
class vcsn::xalloc< StoredType >

Allocate slots in std::ostreams.

Used to store flags in streams.

Set, get or swap data. The idea is to build the right inner class with set, get or swap methods, then use this class as a parameter of operator<<.
