RandomSequencer< GEN > Class Template Reference

#include "lib/random.hpp"

Description

template<class GEN>
class lib::RandomSequencer< GEN >

Access point to a selection of random number sources.

For each kind of performance or usage, a common execution scheme is established to initiate generated number sequences, allowing for seemingly random yet reproducible behaviour — or for actually contingent behaviour when necessary. Client code should rely on Dependency-Injection or the static accessors.
