org.klomp.snark.v2.PieceLayers

All Implemented Interfaces:

Serializable, Cloneable, Map<MerkleHash,List<MerkleHash>>, NavigableMap<MerkleHash,List<MerkleHash>>, SequencedMap<MerkleHash,List<MerkleHash>>, SortedMap<MerkleHash,List<MerkleHash>>

public class PieceLayers
extends TreeMap<MerkleHash,List<MerkleHash>>

A map for the 'piece layers' dictionary, since a standard map with a byte[] for keys is awkward in Java, as is converting the byte arrays to strings.

Since:

0.9.71
