}Meta Marked Data (MMD) is a way to store any type of data in binary.
DBO comes with a MMD buffer creator and parser.
import { MMD } from "../out/MetaMarkedData.js";
import { TNM } from "../out/NodeMaker.js";
const mmdData = TNM.object({
v0: TNM.array([
TNM._8ui(1),
TNM.object({
v0: TNM.typedArray("16ui", [1, 2, 3, 4]),
}),
]),
v1: TNM._32f(12.12),
v2: TNM._16ui(1212),
v3: TNM.string("value 3"),
v4: TNM.typedArray("16ui", [1, 2, 3, 4, 5, 6, 7, 8]),
v5: TNM.stringArray(["hello", "sup"]),
});
const buffer = MMD.parser.toBuffer(mmdData);
console.log(buffer);
const object = MMD.parser.toObject(buffer);
console.log(TNM.toJSONString(object));The result is:
ArrayBuffer {
[Uint8Contents]: <00 03 08 02 00 76 00 30 06 0a 01 03 08 02 00 76 00 30 18 0c 00 00 00 04 00 01 00 02 00 03 00 04 04 07 08 02 00 76 00 31 0d 41 41 eb 85 08 02 00 76 00 32 0c 04 bc 08 02 00 76 00 33 15 00 00 00 07 00 76 00 61 00 6c 00 75 00 65 00 20 00 33 08 02 00 76 00 34 18 0c 00 00 00 08 00 01 00 02 00 03 00 04 00 ... 44 more bytes>,
