Constructor Detail

• FakeRustBackend

  FakeRustBackend(Integer networkId, List<JniBlockMeta> metadata)

Method Detail

• getDataDbFile

   File getDataDbFile()

• getNetworkId

   Integer getNetworkId()

• getMetadata

   final List<JniBlockMeta> getMetadata()

• writeBlockMetadata

   Unit writeBlockMetadata(List<JniBlockMeta> blockMetadata)

• rewindToHeight

   JniRewindResult rewindToHeight(Long height)

• putSubtreeRoots

   Unit putSubtreeRoots(Long saplingStartIndex, List<JniSubtreeRoot> saplingRoots, Long orchardStartIndex, List<JniSubtreeRoot> orchardRoots)

• updateChainTip

   Unit updateChainTip(Long height)

• getFullyScannedHeight

   Long getFullyScannedHeight()

  Returns the height to which the wallet has been fully scanned.

  This is the height for which the wallet has fully trial-decrypted this and all preceding blocks above the wallet's birthday height.

• getMaxScannedHeight

   Long getMaxScannedHeight()

  Returns the maximum height that the wallet has scanned.

  If the wallet is fully synced, this will be equivalent to getFullyScannedHeight; otherwise the maximal scanned height is likely to be greater than the fully scanned height due to the fact that out-of-order scanning can leave gaps.

• getWalletSummary

   JniWalletSummary getWalletSummary()

• suggestScanRanges

   List<JniScanRange> suggestScanRanges()

• getLatestCacheHeight

   Long getLatestCacheHeight()

• getTotalTransparentBalance

   Long getTotalTransparentBalance(String address)

• putUtxo

   Unit putUtxo(ByteArray txId, Integer index, ByteArray script, Long value, Long height)

• setTransactionStatus

   Unit setTransactionStatus(ByteArray txId, Long status)

• findBlockMetadata

   JniBlockMeta findBlockMetadata(Long height)

• rewindBlockMetadataToHeight

   Unit rewindBlockMetadataToHeight(Long height)

• initBlockMetaDb

   Integer initBlockMetaDb()

• proposeTransferFromUri

   ProposalUnsafe proposeTransferFromUri(ByteArray accountUuid, String uri)

• proposeTransfer

   ProposalUnsafe proposeTransfer(ByteArray accountUuid, String to, Long value, ByteArray memo)

• proposeShielding

   ProposalUnsafe proposeShielding(ByteArray accountUuid, Long shieldingThreshold, ByteArray memo, String transparentReceiver)

• createProposedTransactions

   List<ByteArray> createProposedTransactions(ProposalUnsafe proposal, ByteArray unifiedSpendingKey)

• createPcztFromProposal

   ByteArray createPcztFromProposal(ByteArray accountUuid, ProposalUnsafe proposal)

  Creates a partially-created (unsigned without proofs) transaction from the given proposal.

  Do not call this multiple times in parallel, or you will generate PCZT instances that, if finalized, would double-spend the same notes.

• redactPcztForSigner

   ByteArray redactPcztForSigner(ByteArray pczt)

  Redacts information from the given PCZT that is unnecessary for the Signer role.

• pcztRequiresSaplingProofs

   Boolean pcztRequiresSaplingProofs(ByteArray pczt)

  Checks whether the caller needs to have downloaded the Sapling parameters.

• addProofsToPczt

   ByteArray addProofsToPczt(ByteArray pczt)

  Adds proofs to the given PCZT.

• extractAndStoreTxFromPczt

   ByteArray extractAndStoreTxFromPczt(ByteArray pcztWithProofs, ByteArray pcztWithSignatures)

  Takes a PCZT that has been separately proven and signed, finalizes it, and stores it in the wallet.

• decryptAndStoreTransaction

   ByteArray decryptAndStoreTransaction(ByteArray tx, Long minedHeight)

• initDataDb

   Integer initDataDb(ByteArray seed)

  Sets up the internal structure of the data database.

  If seed is null, database migrations will be attempted without it.

• getAccounts

   List<JniAccount> getAccounts()

• getAccountForUfvk

   JniAccount getAccountForUfvk(String ufvk)

• createAccount

   JniAccountUsk createAccount(String accountName, String keySource, ByteArray seed, ByteArray treeState, Long recoverUntil)

• importAccountUfvk

   JniAccount importAccountUfvk(String accountName, String keySource, String ufvk, ByteArray treeState, Long recoverUntil, Integer purpose, ByteArray seedFingerprint, Long zip32AccountIndex)

• isSeedRelevantToAnyDerivedAccounts

   Boolean isSeedRelevantToAnyDerivedAccounts(ByteArray seed)

• isValidSaplingAddr

   Boolean isValidSaplingAddr(String addr)

• isValidTransparentAddr

   Boolean isValidTransparentAddr(String addr)

• isValidUnifiedAddr

   Boolean isValidUnifiedAddr(String addr)

• isValidTexAddr

   Boolean isValidTexAddr(String addr)

• getCurrentAddress

   String getCurrentAddress(ByteArray accountUuid)

• getSingleUseTransparentAddress

   JniSingleUseTransparentAddress getSingleUseTransparentAddress(ByteArray accountUuid)

• getNextAvailableAddress

   String getNextAvailableAddress(ByteArray accountUuid, Integer receiverFlags)

• getTransparentReceiver

   String getTransparentReceiver(String ua)

• getSaplingReceiver

   String getSaplingReceiver(String ua)

• listTransparentReceivers

   List<String> listTransparentReceivers(ByteArray accountUuid)

• getBranchIdForHeight

   Long getBranchIdForHeight(Long height)

• getMemoAsUtf8

   String getMemoAsUtf8(ByteArray txId, Integer protocol, Integer outputIndex)

• scanBlocks

   <ERROR CLASS> scanBlocks(Long fromHeight, ByteArray fromState, Long limit)

• transactionDataRequests

   List<JniTransactionDataRequest> transactionDataRequests()

• fixWitnesses

   Unit fixWitnesses()

  This function calls check_witnesses and queue_rescans from the underlying librustzcash internally. This method is intended for repairing wallets that broke due to bugs in shardtree.

  check_witnesses: It attempts to construct a witness for each note belonging to the wallet that is believed by the wallet to currently be spendable, and returns a vector of the ranges that must be rescanned in order to correct missing witness data.

  queue_rescans: Updates the scan queue by inserting scan ranges for the given range of block heights, with the specified scanning priority.
