CBOR Java library

The Concise Binary Object Representation (CBOR) is a data format whose design goals include the possibility of extremely small code size, fairly small message size, and extensibility without the need for version negotiation

Examples

decode integer

Stringinput = "1b000000e8d4a51000";
byte[] bytes = fromHex(input);
CBORDecoderdecoder = newCBORDecoder();
CBORObjectresult = decoder.decode(bytes);
assertTrue(result.valinstanceofLong);
assertEquals(1000000000000L, result.val);

decode bytes

Stringinput = "5818010203040102030401020304010203040102030401020304";
byte[] bytes = fromHex(input);
CBORDecoderdecoder = newCBORDecoder();
CBORObjectresult = decoder.decode(bytes);
assertTrue(result.valinstanceofbyte[]);
byte[] checkBytes = {0x01, 0x02, 0x03, 0x04, 0x01, 0x02, 0x03, 0x04, 0x01, 0x02, 0x03, 0x04, 0x01, 0x02, 0x03, 0x04, 0x01, 0x02, 0x03, 0x04, 0x01, 0x02, 0x03, 0x04};
byte[] resultBytes = (byte[]) result.val;
for (inti = 0; i < resultBytes.length; i++) {
assertEquals(checkBytes[i], resultBytes[i]);
}

decode array

Stringinput = "83010203";
byte[] bytes = fromHex(input);
CBORDecoderdecoder = newCBORDecoder();
CBORObjectresult = decoder.decode(bytes);
assertTrue(result.valinstanceofArrayList);
ArrayListitems = (ArrayList) result.val;
assertEquals(1L, items.get(0));
assertEquals(2L, items.get(1));
assertEquals(3L, items.get(2));
