Constructor Detail

PatchworkProbeMsg

public PatchworkProbeMsg(NodeId peer,
                         int totalSize,
                         int type,
                         boolean response)

Constucts a probing message of a certain type, with a given approximate size. The size needs to be at least MINIMUM_SIZE, and if difference between it and MINIMUM_SIZE is not divisible by 4 it will be rounded down to a number that is.

Parameters:

peer - the node to probe

totalSize - how big the message should be

type - the type of the message

response - whether this is a response
