Example 1 with CoinSelection

use of co.rsk.bitcoinj.wallet.CoinSelection in project rskj by rsksmart.

the class RskAllowUnconfirmedCoinSelector method select.

@Override

    ArrayList<TransactionOutput> sortedOutputs = new ArrayList<TransactionOutput>(candidates);
    // TODO: Take in network parameters when instanatiated, and then test against the current network. Or just have a boolean parameter for "give me everything"
    if (!target.equals(NetworkParameters.MAX_MONEY)) {
        sortOutputs(sortedOutputs);
    }

    // bit over (excessive value will be change).
