  • All Superinterfaces:

    public interface CheckedListProof<E>
extends CheckedProof
    A proof that some elements exist in a proof list. Example usage: 
    
 HashCode expectedIndexHash = // get a known index hash from block proof //
 UncheckedListProof proof = new UncheckedListProofAdapter(rootProofNode, serializer);
 // Check the proof
 CheckedListProof checkedProof = proof.check();
 // Check the index hash
 if (checkedProof.isValid() && checkedProof.getIndexHash().equals(expectedIndexHash)) {
   // Get and use elements
   NavigableMap value = checkedProof.getElements();
 }

    • Method Detail

      • getElements

        NavigableMap<Long,​E> getElements()
        Get all list proof elements. There might be several consecutive ranges.
        Returns:
        list proof elements. Empty if the proof is a proof of absence
        Throws:
        IllegalStateException - if the proof is not valid
