Interface Nonce

public interface Nonce

A nonce. Each nonce contains scoops. Each scoop contains a pair of hashes.

Method Summary

Modifier and Type	Method	Description
void	dumpInto(FileChannel where, int metadataSize, long offset, long length)	Dumps this nonce into the give file, as the offsetth nonce inside the file.
Deadline	getDeadline(DeadlineDescription description)	Yields the deadline of this nonce, with the given description.

Method Details

dumpInto

void dumpInto(FileChannel where,
 int metadataSize,
 long offset,
 long length)
       throws IOException

Dumps this nonce into the give file, as the offsetth nonce inside the file.

Parameters:

where - the file channel where the nonce must be dumped

metadataSize - the size of the metadata of the plot file, that precedes the nonces

offset - the progressive number of the nonce inside the file; for instance, if the file will contains nonces from progressive 100 to progressive 150, then they are placed at offsets from 0 to 50 inside the file, respectively

length - the total number of nonces that will be contained in the file

Throws:

IOException - if the nonce could not be dumped into the file

getDeadline

Deadline getDeadline(DeadlineDescription description)

Yields the deadline of this nonce, with the given description.

Parameters:

description - the description of requested deadline

Returns:

the deadline

Throws:

IllegalArgumentException - if the hashing algorithm in description does not match that used in plot file for this nonce
