to_bytes(byte[] data,
int[] offset)
Store the object in its "on the wire" form in the byte array
data , starting at index offset [0] , and
increment offset [0] by the number of bytes written;
if data == null , increment offset [0] by
the number of bytes that would have been written otherwise. |

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

to_bytes
public void to_bytes(byte[] data,
int[] offset)
- Description copied from interface:
QuickSerializable
- Store the object in its "on the wire" form in the byte array
data
, starting at index offset [0]
, and
increment offset [0]
by the number of bytes written;
if data == null
, increment offset [0]
by
the number of bytes that would have been written otherwise.
- Overrides:
to_bytes
in class NetworkMessage
- Following copied from interface:
ostore.util.QuickSerializable
- Parameters:
data
- The byte array to store into, or null
.offset
- A single element array whose first
element is the index in data to begin writing at on
function entry, and which on function exit has been
incremented by the number of bytes written.
