Detailed Description

template<class RAIter, class Generator>
class ripple::test::csf::Selector< RAIter, Generator >

Invocable that returns random samples from a range according to a discrete distribution.

Given a pair of random access iterators begin and end, each call to the instance of Selector returns a random entry in the range (begin,end) according to the weights provided at construction.
