Package com.exonum.binding.common.proofs.list

Class CheckedListProofImpl<E>

java.lang.Object

com.exonum.binding.common.proofs.list.CheckedListProofImpl<E>

All Implemented Interfaces:

CheckedProof, CheckedListProof

public class CheckedListProofImpl<E>
extends Object
implements CheckedListProof

A checked list proof includes list proof verification results.

If it is correct you may access:

• a calculated Merkle root hash
• proof elements

If the proof is not valid, you may get the verification status using getProofStatus() with description of why the proof is not valid.

CheckedListProofImpl

public CheckedListProofImpl(HashCode calculatedRootHash,
                            NavigableMap<Long,E> elements,
                            ListProofStatus proofStatus)

Creates checked list proof.

Parameters:

calculatedRootHash - calculated root hash of the proof

elements - proof elements collection

proofStatus - a status of proof verification

Method Detail

getElements

public NavigableMap<Long,E> getElements()

Description copied from interface: CheckedListProof

Get all list elements. There might be several consecutive ranges.

Specified by:

getElements in interface CheckedListProof<E>

getRootHash

public HashCode getRootHash()

Description copied from interface: CheckedProof

Returns the calculated root hash of the proof. Must be equal to the Merkle root hash of the collection, providing this proof.

Specified by:

getRootHash in interface CheckedProof

getProofStatus

public ListProofStatus getProofStatus()

Description copied from interface: CheckedListProof

Returns the status of this proof: whether it is structurally valid.

Specified by:

getProofStatus in interface CheckedListProof<E>

Specified by:

getProofStatus in interface CheckedProof

isValid

public boolean isValid()

Description copied from interface: CheckedProof

Returns true if proof status is valid, false otherwise. Details about the proof verification status could be obtained via CheckedProof.getProofStatus().
