Actionscript Byte Arrays

Question

I am writing alot of single bytes into a byte Array. Is there any way to compact this and write them all at once?

myByteArray.writeByte(0x00);
myByteArray.writeByte(0x00);
myByteArray.writeByte(0x00);
myByteArray.writeByte(0x01);
myByteArray.writeByte(0x00);
myByteArray.writeByte(0x10);

Could create a Vector and list your values there, then just write them in from there.

var values:Vector.<uint> = new <uint>[0x00, 0x00, 0x00, 0x00, 0x01, 0x00, 0x10];

for each(var i:uint in values)
{
    myByteArray.writeByte(i);
}

Another option, if you are doing this a lot, is to create a file that has the sequence of bytes that you want, embed that file into your swf as a byte array, and then use .writeBytes(). Something like:

[Embed(source="data.dat", mimeType="application/octet-stream")]
private const Fragment:Class;

And then:

var wad:ByteArray = new Fragment() as ByteArray;
myByteArray.writeBytes(wad);

ByteArray does not support [] notation. The only thing, that comes to my mind is the following:

var myByteArray:ByteArray=new ByteArray();
var tempArr:Array=[0x00, 0x00, 0x00, 0x01, 0x00, 0x10];
for each (var elem:int in tempArr)
    myByteArray.writeByte(elem);

Feel free to vote this down, as this is utterly ridiculous :).

myByteArray.writeUnsignedInt(0x00 << 24 | 0x00 << 16 | 0x00 << 8 | 0x01);

You would save 3 function calls :)
