Throws:

ProtocolException

Ping

public Ping(long nonce)

Create a Ping with a nonce value. Only use this if the remote node has a protocol version > 60000

Ping

public Ping()

Create a Ping without a nonce value. Only use this if the remote node has a protocol version <= 60000

Method Detail

bitcoinSerializeToStream

public void bitcoinSerializeToStream(OutputStream stream)
                              throws IOException

Description copied from class: Message

Serializes this message to the provided stream. If you just want the raw bytes use bitcoinSerialize().

Throws:

IOException

parseLite

protected void parseLite()

Description copied from class: Message

Perform the most minimal parse possible to calculate the length of the message payload. This is only required for subclasses of ChildMessage as root level messages will have their length passed into the constructor.

Implementations should adhere to the following contract: If parseLazy = true the 'length' field must be set before returning. If parseLazy = false the length field must be set either within the parseLite() method OR the parse() method. The overriding requirement is that length must be set to non UNKNOWN_MESSAGE value by the time the constructor exits.

hasNonce

public boolean hasNonce()

getNonce

public long getNonce()
