LITTLE_ENDIAN - does not work!

[GoogleCodeExporter]

Your System almost works!!! BUT Conversion with little endian does not work. It 
seems like you forgot to impliment byteorder when unpacking?? It is really 
unfortunate because I am soo close to get it working a serial protocol for 
arduino. 

You can reproduce the problem with the code below:


@StructClass
public class Foo{
    @StructField(order = 0)
    public int b;
    @StructField(order = 1)
    public int i;
}

try{
    // Pack the class as a byte buffer
    Foo f = new Foo();
    f.b = (int)14;
    f.i = 12;
    byte[] b = JavaStruct.pack(f,ByteOrder.LITTLE_ENDIAN );

    // Unpack it into an object
    Foo f2 = new Foo();
    JavaStruct.unpack(f2, b,ByteOrder.LITTLE_ENDIAN );
    println(f2.b);
}
catch(StructException e){
}
  et_begin();
  size(800, 600);
}

Since we are only using short (8bit = 2 bytes) we have solved it with this 
nasty solution:

 try {
    // Pack the class as a byte buffer
    Foo f = new Foo();
    f.b = (int)14;
    f.i = 12;
    byte[] b = JavaStruct.pack(f, ByteOrder.LITTLE_ENDIAN );
    byte[] c = new byte[b.length];
  /*  for(int i =0; i < b.length;i++)
    {
      c[i] = b[b.length -i-1];

    }*/
    for(int i=0; i < b.length-1;i=i+2)
    {
      c[i] = b[i+1];
      c[i+1] = b[i];
    }
    // Unpack it into an object
    Foo f2 = new Foo();
    JavaStruct.unpack(f2, c );
    println(f2.b);
  }
  catch(StructException e) {
  }
