This is not a templated class on purpose. Actually sometimes, the actual content of the Fifo doesn't matter, or it may be shared by several data structures. So this class only focus on maintaining read and write indexes.
Parameters -depth, int, default 8, fifo capacity that is always rounded to a power of 2 -debug, int, default 0.

is called to finalize restart. On restart, one shall update pointers, or reopen ressources (files, ...).
Most of pointers are restored by the thanks to the post++ library provided that the CLASSINFO() was correctly set.
However, some pointers are not relocated by the library. These are for example the method pointers used for the processes. Take a look at
Reimplemented in Sampa::Bridge, Sampa::Dma, Sampa::FixLatencySlave, Sampa::PeriodicTrafficGenerator, Sampa::TwoPortL1Cpu, and Sampa::StochasticCpu.
