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 probetotalSize
- how big the message should betype
- the type of the messageresponse
- whether this is a response
