Interface UncheckedMapProof

  • All Known Implementing Classes:
    UncheckedFlatMapProof
    public interface UncheckedMapProof
    An unchecked map proof. It's used to get a checked map proof. Example usage: 
    
 byte[] key = "The key for which I want a proved value".getBytes();
 HashCode expectedRootHash = // get a known root hash from block proof //
 UncheckedMapProof proof = requestProofForKey(key);
 // Convert to checked
 CheckedMapProof checkedProof = proof.check();
 // Check the root hash
 if (checkedProof.compareWithRootHash(expectedRootHash)) {
   // Get and use the value(s)
   byte[] value = checked.get(key);
 }
