Example 1 with RLPItem

use of org.aion.rlp.RLPItem in project aion by aionnetwork.

the class TrieImpl method deserialize.

public void deserialize(byte[] data) {
    synchronized (cache) {
        RLPList rlpList = (RLPList) RLP.decode2(data).get(0);
        RLPItem keysElement = (RLPItem) rlpList.get(0);
        RLPList valsList = (RLPList) rlpList.get(1);
        RLPItem root = (RLPItem) rlpList.get(2);
        for (int i = 0; i < valsList.size(); ++i) {
            byte[] val = valsList.get(i).getRLPData();
            byte[] key = new byte[32];
            Value value = Value.fromRlpEncoded(val);
            System.arraycopy(keysElement.getRLPData(), i * 32, key, 0, 32);
            cache.getNodes().put(wrap(key), new Node(value));
        }
        this.deserializeRoot(root.getRLPData());
    }
