createFakeTxWithChangeAddress

public static Transaction createFakeTxWithChangeAddress(NetworkParameters params,
                                                        Coin value,
                                                        Address to,
                                                        Address changeOutput)

Create a fake TX of sufficient realism to exercise the unit tests. Two outputs, one to us, one to somewhere else to simulate change. There is one random input.

createFakeTx

public static Transaction createFakeTx(NetworkParameters params,
                                       Coin value,
                                       Address to)

Create a fake TX of sufficient realism to exercise the unit tests. Two outputs, one to us, one to somewhere else to simulate change. There is one random input.

createFakeTx

public static Transaction createFakeTx(NetworkParameters params,
                                       Coin value,
                                       ECKey to)

Create a fake TX of sufficient realism to exercise the unit tests. Two outputs, one to us, one to somewhere else to simulate change. There is one random input.

createFakeTx

public static Transaction[] createFakeTx(NetworkParameters params,
                                         Coin value,
                                         Address to,
                                         Address from)

Transaction[0] is a feeder transaction, supplying BTC to Transaction[1]

roundTripTransaction

public static Transaction roundTripTransaction(NetworkParameters params,
                                               Transaction tx)

Roundtrip a transaction so that it appears as if it has just come from the wire

createFakeDoubleSpendTxns

public static FakeTxBuilder.DoubleSpends createFakeDoubleSpendTxns(NetworkParameters params,
                                                                   Address to)

Creates two transactions that spend the same (fake) output. t1 spends to "to". t2 spends somewhere else. The fake output goes to the same address as t2.

createFakeBlock

public static FakeTxBuilder.BlockPair createFakeBlock(BlockStore blockStore,
                                                      long timeSeconds,
                                                      Transaction... transactions)

Emulates receiving a valid block that builds on top of the chain.

createFakeBlock

public static FakeTxBuilder.BlockPair createFakeBlock(BlockStore blockStore,
                                                      Transaction... transactions)

makeSolvedTestBlock
