Constructor Detail

BitsToFile

BitsToFile(java.io.FileOutputStream fstreamOut)

Constructor.

Parameters:

FileOutputStream - The stream to the file you want to write to.

Method Detail

finishUp

int finishUp()

When we get to the end of a file, we need to write the last vector, even though it may not be full. So I use this method to write zeros after the data that has been put in so far. Then I can call execute and everything will be okay. I just call it on a new vector with a zero in it. This is so the execute method will actually go through the for loop once.

execute

void execute(java.util.Vector oneCode)

Writes a vector of bits to the file.

Parameters:

Vector - The vector of bits to write to the file.
