                    byte[] payloadBytes)

UTXOsMessage

public UTXOsMessage(NetworkParameters params,
                    List<TransactionOutput> outputs,
                    long[] heights,
                    Sha256Hash chainHead,
                    long height)

Provide an array of output objects, with nulls indicating that the output was missing. The bitset will be calculated from this.

Method Detail

parseLite

protected void parseLite()
                  throws ProtocolException

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.

Specified by:

ProtocolException
