RE: Passing a data structure as a byte array

["David Morris" <David.Morris@xxxxxxxxxxxxx>]

Joe,

You haven't shown what you tried but this worked for me:

package demo;

import java.io.File;
import java.io.FileOutputStream;
import java.io.PrintStream;


/**

public class TestByteParm {
    public TestByteParm() {
        try {
            File tmpDir = new File("/tmp");
            File tempFile = File.createTempFile("stdout", "", tmpDir);
            System.setOut(new PrintStream(new
FileOutputStream(tempFile)));
        }
        catch (Throwable t) {
            System.err.println("Error overriding standard output to
file.");
            t.printStackTrace(System.err);
        }

    }
        public byte[] method(byte[] data) {
                System.out.println(data.toString());
                data[8] = 'x';
                return data;
        }
}

When I run this I get back my original value with Hxllo.

Okay, it looks like I'll do this using a character value.  However,
I'd
still like to figure out how to pass a data structure with no
conversion.  More importantly, I'd like to pass that structure in,
modify it, and return it.

Does anybody have any ideas?
