class ShardedMap[A, B] extends HashMap[A, B]

A class representing maps from A to B, using sharding and synchronized blocks. The hashes are memoized, and also used to record deleted values.

Instance Constructors

  1. new ShardedMap()(implicit arg0: ClassTag[A], arg1: ClassTag[B])

  2. new ShardedMap(shards: Int, initSize: Int)(implicit arg0: ClassTag[A], arg1: ClassTag[B])

    shards

    the number of shards.

    initSize

    the initial size of each shard; this must be a power of 2 shards and initSize should be coprime.
