Method Detail

onBlocksDownloaded

public void onBlocksDownloaded(Peer peer,
                               Block block,
                               @Nullable
                               FilteredBlock filteredBlock,
                               int blocksLeft)

Deprecated.

Description copied from interface: BlocksDownloadedEventListener

Called on a Peer thread when a block is received.

The block may be a Block object that contains transactions, a Block object that is only a header when fast catchup is being used. If set, filteredBlock can be used to retrieve the list of associated transactions.

Specified by:

onBlocksDownloaded in interface BlocksDownloadedEventListener

Parameters:

peer - the peer receiving the block

block - the downloaded block

filteredBlock - if non-null, the object that wraps the block header passed as the block param.

blocksLeft - the number of blocks left to download

onChainDownloadStarted

public void onChainDownloadStarted(Peer peer,
                                   int blocksLeft)

Deprecated.

Description copied from interface: ChainDownloadStartedEventListener

Called when a download is started with the initial number of blocks to be downloaded.

Specified by:

onChainDownloadStarted in interface ChainDownloadStartedEventListener

Parameters:

peer - the peer receiving the block

blocksLeft - the number of blocks left to download

onPreMessageReceived

public Message onPreMessageReceived(Peer peer,
                                    Message m)

Deprecated.

Description copied from interface: PreMessageReceivedEventListener

Called when a message is received by a peer, before the message is processed. The returned message is processed instead. Returning null will cause the message to be ignored by the Peer returning the same message object allows you to see the messages received but not change them. The result from one event listeners callback is passed as "m" to the next, forming a chain.

Note that this will never be called if registered with any executor other than Threading.SAME_THREAD

Specified by:

onPreMessageReceived in interface PreMessageReceivedEventListener

getData

public java.util.List<Message> getData(Peer peer,
                                       GetDataMessage m)

Deprecated.

Description copied from interface: GetDataEventListener

Called when a peer receives a getdata message, usually in response to an "inv" being broadcast. Return as many items as possible which appear in the GetDataMessage, or null if you're not interested in responding.

Note that this will never be called if registered with any executor other than Threading.SAME_THREAD

Specified by:

getData in interface GetDataEventListener
