truncateOrExpand

public static void truncateOrExpand(FileChannel channel,
 long size)
                             throws IOException

Unlike FileChannel.truncate(long size), this implementation extends the file if it is shorter by using zero bytes as defined in the POSIX standard.

Parameters:

channel - channel's file

size - target size

Throws:

IOException - If an exception occurs during truncate or write.
