RandomSampler

:: DeveloperApi :: A pseudorandom sampler. It is possible to change the sampled item type. For example, we might want to add weights for stratified sampling or importance sampling. Should only use transformations that are tied to the sampler and cannot be applied after sampling.

T: item type
U: sampled item type

Abstract Value Members

abstract def sample(): Int

Whether to sample the next item or not.
Whether to sample the next item or not. Return how many times the next item will be sampled. Return 0 if it is not sampled.
