    • 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

      public 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
