reading bytes without offset

[dcodeIO]

Assuming that buf has been filled and properly flipped

var w = buf.readUint32() // also no offset
var x = buf.readUint32()
var y = buf.readUint32()
var z = buf.readUint32()

will read one Uint32 after another (relative). This is equal to (absolute):

var w = buf.readUint32(0)
var x = buf.readUint32(4)
var y = buf.readUint32(8)
var z = buf.readUint32(12)
buf.offset = 16;

Regarding byte order: Once set to LE, all operations following will use LE until you set it to BE again.

buf.LE();
...
...
...
buf.BE();

Yea, I realized. Got it solved. Except I don't get why I should properly FLIP it? What is the implications of flip? I didn't use flip but I'm getting proper results.

Thanks though, this is great :)

If you just wrap some data, flipping is not necessary. It is, though, if you fill the buffer successively just like you read it in the example above:

var buf = new ByteBuffer(6); // initializes with offset = 0, limit = 6
buf.writeUint32(123); // afterwards: offset = 4, limit = 6
buf.flip(); // afterwards: limit = offset = 4, offset = 0, ready for read operations
