[s]I can’t figure out why this isn’t writing/reading properly.
Basically what I’m trying to do is write numbers to an array of bytes, and then read them. It’s pretty self-explanatory if you take a look.
Any help would be greatly appreciated.[/s]
Test.java:
import org.valhalla.io.Payload;
public class Test
{
public Test()
{
try {
Payload p = new Payload(32);
p.putLong(0x7fffffffffffffffL);
p.putInt(0xFFFFFF);
p.putShort(0xFFFF);
p.put(0xFF);
p.putFloat(1.234f);
p.reset(); // Resets the position back to zero.
System.out.println("Value: " + p.getLong() + ", " + p.getInt() + ", " + p.getShort() + ", " + p.get() + ", " + p.getFloat());
} catch (Exception e) {
e.printStackTrace();
}
}
public static void main(String[] args) {
new Test();
}
}
Output:
Value: -1, 16777215, 65535, 255, 1.234
