I want to create a file stream in memory. In my case it's a midifile.
This file has a specified format. The header and other blocks have
variables of different types. A byte[] buffer is associated to the
class. My question now is how can I easily write my different variables
sequentially into the buffer? How will the headerChunk.write() function
look like? Here comes a little excerpt.
TIA,
Hans
public class MidiFile extends ByteArrayInputStream {
class headerChunk {
final byte[] Id = { 'M', 'T', 'h', 'd' };
final int Size = 6;
short Format = 0;
short NumTracks = 1;
short TimeDiv;
void write(....); ????
}
}

Hello Hans,
There are two classes that will help you, DataInputStream and
DataOutputStream. These classes let an application read primitive Java
data types from an underlying input stream in a machine-independent way.
Hope it helps you!

David Marques

Hi David,
it's you again to give me tips. I've got it runnning now, not quite in a
manner which I hoped, but it works reliably.
Thanks and Merry Christmas,
Hans
