Field Detail

LOOP_BREAK

public static final int LOOP_BREAK

number of times the check-loop will be repeated without any changes, until it will be breaked. A BufferedWriter normally writes 8192 bytes a time, so with a nice 56k modem this can take more than 2 seconds! But the check is performed 100 times per second, so at least 200-400 loops should be granted.

Constructor Detail

public FileSizeChecker(java.io.File f,
                       int minimalSize)

Parameters:

f - the file to check

minimalSize - minimal filesize in bytes

Method Detail

run

public void run()

loop as long as the file hasn't reached the minimalSize. As soon as the wanted filesize is reached, this thread is stopped and the programm can continue.
Make sure that the file will reache the specified size, otherwise this won't stop!!
