org.bitcoinj.jni.NativeWalletCoinsReceivedEventListener

All Implemented Interfaces:

WalletCoinsReceivedEventListener

public class NativeWalletCoinsReceivedEventListener
extends Object
implements WalletCoinsReceivedEventListener

An event listener that relays events to a native C++ object. A pointer to that object is stored in this class using JNI on the native side, thus several instances of this can point to different actual native implementations.

                            Transaction tx,
                            Coin prevBalance,

Description copied from interface: WalletCoinsReceivedEventListener

This is called when a transaction is seen that sends coins to this wallet, either because it was broadcast across the network or because a block was received. If a transaction is seen when it was broadcast, onCoinsReceived won't be called again when a block containing it is received. If you want to know when such a transaction receives its first confirmation, register a TransactionConfidence event listener using the object retrieved via Transaction.getConfidence(). It's safe to modify the wallet in this callback, for example, by spending the transaction just received.

Specified by:

onCoinsReceived in interface WalletCoinsReceivedEventListener

Parameters:

wallet - The wallet object that received the coins

tx - The transaction which sent us the coins.

prevBalance - Balance before the coins were received.

newBalance - Current balance of the wallet. This is the 'estimated' balance.
