Class IndexProof

java.lang.Object
com.exonum.binding.core.blockchain.proofs.IndexProof
public abstract class IndexProof
extends java.lang.Object
Proof of authenticity for a single index in the database.

It is comprised of a BlockProof and a MapProof from the collection aggregating the index hashes of proof indexes for an index with a certain full name.

If an index does not exist in the database, then the MapProof will prove its absence.
