メソッドの詳細

nextSeed

public abstract int nextSeed()

Return a new seed.

shuffle

public abstract List<ShardRouting> shuffle(List<ShardRouting> shards,
                                           int seed)

Return a shuffled view over the list of shards. The behavior of this method must be deterministic: if the same list and the same seed are provided twice, then the result needs to be the same.

public List<ShardRouting> shuffle(List<ShardRouting> shards)

Equivalent to calling shuffle(shards, nextSeed()).
