Yes, thank you. FWIW, I use these when I am working with WebGL. However,
the fact that I need to use (new) for each member converting the
following struct:
____________________________
struct someStruct {
unsigned long id;
char username[16];
float amountDue;
};
____________________________
to the following typed array representation:
____________________________
var buffer = new ArrayBuffer(24);
// ... read the data into the buffer ...
var idView = new Uint32Array(buffer, 0, 1);
var usernameView = new Uint8Array(buffer, 4, 16);
var amountDueView = new Float32Array(buffer, 20, 1);
____________________________
Is still troublesome. I will do some benchmarks wrt looping through
functional ops, and their intrusive equivalents. AFAICT, the intrusive
technique basically has to win. :^o
