All Implemented Interfaces:

Serializable

Enclosing class:

IsmFormat

public static class IsmFormat.IsmShardCoder
extends AtomicCoder<IsmFormat.IsmShard>

A coder for IsmFormat.IsmShards.

The shard descriptor is encoded as:

• id (variable length integer encoding)
• blockOffset (variable length long encoding)
• indexOffset (variable length long encoding)
