示例1: rowHash
import org.apache.cassandra.utils.FBUtilities; //导入方法依赖的package包/类
private MerkleTree.RowHash rowHash(AbstractCompactedRow row)
{
validated++;
// MerkleTree uses XOR internally, so we want lots of output bits here
CountingDigest digest = new CountingDigest(FBUtilities.newMessageDigest("SHA-256"));
row.update(digest);
// only return new hash for merkle tree in case digest was updated - see CASSANDRA-8979
if (digest.count > 0)
{
return new MerkleTree.RowHash(row.key.getToken(), digest.digest(), digest.count);
}
else
{
return null;
