构造器详细资料

MerkleTree

public MerkleTree(List<String> leafSignatures)

Use this constructor to create a MerkleUtil from a list of leaf signatures. The Merkle tree is built from the bottom up.

参数:

leafSignatures - List

MerkleTree

public MerkleTree(MerkleTree.BinaryNode treeRoot,
                  int numNodes,
                  int height,
                  List<String> leafSignatures)

Use this constructor when you have already constructed the tree of Nodes (from deserialization).

参数:

treeRoot -

numNodes -

height -

leafSignatures -
