		D	dist,
		RNG &	rng,
		Map< std::string, DSType< D >> &	map_
	)

Either samples a value from the specified distribution or observes a value against it, depending on whether there is data at the corresponding address in the passed Map<std::string, DSType<D>>.

Template Parameters

Map	map type with string keys and values of type mapped to by dist.sample.
D	The type of distribution from which to sample
RNG	The type of PRNG to use
Ts	The distribution types contained in the passed record

Parameters

r	the record into which to sample
address	the address at which to sample
dist	the distribution from which to draw sample(s)
rng	the PRNG to use for sampling
map_	map from addresses to values.

Returns

DSType<D>
