foundation.omni.txsigner.OmniKeychainSendingService

All Implemented Interfaces:

OmniSendingService

public class OmniKeychainSendingService
extends Object
implements OmniSendingService

A service to sign and send Omni Transactions (similar to functionality in Omni Core). Uses a local HD Keychain (via OmniKeychainSigningService) and a local or remote JSON-RPC server OmniClient to provide this service.

 org.bitcoinj.base.Coin amount)
                                                            throws IOException

Throws:

IOException

 org.bitcoinj.base.Address toAddress,
 CurrencyID currency,
 OmniValue amount)

Find inputs, Sign and Send an Omni Simple Send transaction

This method is compatible with the Omni Core omni_send JSON-RPC method and if made available from a JSON-RPC server should work equivalently. (The last two, optional arguments are not currently implemented.)

Specified by:

omniSend in interface OmniSendingService

Parameters:

fromAddress - Omni address sending funds

toAddress - Omni address receiving funds

currency - Currency type

amount - amount

Returns:

A future for the transaction hash

Throws:

IOException - A failure occurred fetching inputs or broadcasting the transaction

omniSend

public CompletableFuture<org.bitcoinj.base.Sha256Hash> omniSend(UnsignedTxSimpleSend simpleSend)
                                                         throws IOException

Sign and Send an Omni Simple Send transaction

Specified by:

omniSend in interface OmniSendingService

Parameters:

simpleSend - An object holding all the parameters (including UTXO inputs) for a simple send transaction

Returns:

A future for the transaction hash

Throws:

IOException - A failure occurred fetching broadcasting the transaction

getInputsFor

public List<TransactionInputData> getInputsFor(org.bitcoinj.base.Address fromAddress)
                                        throws IOException

Fetch inputs for an address

Specified by:

getInputsFor in interface OmniSendingService

Parameters:

fromAddress - Address with zero or more UTXOs

Returns:

a list of all UTXOs for this address

Throws:

IOException - if an error occurred fetching inputs

sendRawTransactionAsync

public CompletableFuture<org.bitcoinj.base.Sha256Hash> sendRawTransactionAsync(org.bitcoinj.core.Transaction tx)

Specified by:

sendRawTransactionAsync in interface OmniSendingService
