Class MapProof

java.lang.Object

com.exonum.binding.core.storage.indices.MapProof

public abstract class MapProof
extends Object

A view of a ProofMapIndexProxy, i.e., a subset of its entries coupled with a proof, which jointly allow restoring the index hash of the map. Apart from proving the existing entries in the map, MapProof can assert absence of certain keys in the underlying index.

Method Detail

getAsMessage

public abstract com.exonum.messages.proof.MapProofOuterClass.MapProof getAsMessage()

Returns the proof as a protobuf message.

parseFrom

public static MapProof parseFrom(byte[] mapProofMessage)
                          throws com.google.protobuf.InvalidProtocolBufferException

Creates a new MapProof given the serialized map proof message.

Throws:

com.google.protobuf.InvalidProtocolBufferException - if the message is not MapProofOuterClass.MapProof

newInstance

public static MapProof newInstance(com.exonum.messages.proof.MapProofOuterClass.MapProof mapProofMessage)

Creates a new MapProof given the map proof message.
