Method Detail

computeContractTransactionDetail

void computeContractTransactionDetail(TransactionDetail transactionDetail,
                                      Object transactionReceipt)

Compute contract transaction detail from blockchain. The contract address is to be determined from blockchain transaction

Parameters:

transactionDetail -

transactionReceipt -

computeTransactionDetail

TransactionDetail computeTransactionDetail(TransactionDetail transactionDetail,
                                           ContractDetail contractDetail)
                                    throws InterruptedException

compute transaction detail from blockchain. The transaction can be of type contract transaction or a simple ether transaction

Parameters:

transactionDetail -

contractDetail -

Returns:

TransactionDetail object with details retrieved from blockchain

Throws:

InterruptedException

computeTransactionDetail

TransactionDetail computeTransactionDetail(String hash,
                                           ContractDetail contractDetail)
                                    throws InterruptedException

compute a transaction detail from blockchain using the transaction hash and the contract detail to use. The contract detail can be null, thus it will be retrieved from blockchain transaction

Parameters:

hash -

contractDetail -

Returns:

TransactionDetail object with details retrieved from blockchain

Throws:

InterruptedException

checkPendingTransactions

int checkPendingTransactions(long pendingTransactionMaxDays)

checks transactions marked as pending in DB and verify their status on blockchain. If mined, the status gets updated on DB, else wait for next trigger time.

Parameters:

pendingTransactionMaxDays - mas days to keep transactions not sent on blockchain as pending. If equals or less than 0, no duration check

Returns:

number of transactions marked as mined

scanNewerBlocks

void scanNewerBlocks()
              throws InterruptedException,
                     IOException

Scans newly mined blocks in Blockchain to verify if there are transactions on configured token or wallet. If found, save it in DB.

Throws:

InterruptedException

IOException
