Example 21 with CBORParser

use of com.fasterxml.jackson.dataformat.cbor.CBORParser in project jackson-dataformats-binary by FasterXML.

the class BigNumbersTest method _testBigInteger.

private void _testBigInteger(BigInteger expValue) throws Exception {
    final ByteArrayOutputStream sourceBytes = new ByteArrayOutputStream();
    final CBORGenerator sourceGen = cborGenerator(sourceBytes);
    sourceGen.writeNumber(expValue);
    sourceGen.close();
    // but verify that the original content can be parsed
    CBORParser parser = cborParser(sourceBytes.toByteArray());
    assertToken(JsonToken.VALUE_NUMBER_INT, parser.nextToken());
    assertEquals(expValue, parser.getBigIntegerValue());
    // also, coercion to long at least
    long expL = expValue.longValue();
    assertEquals(expL, parser.getLongValue());
    // and int, if feasible
    if (expL >= Integer.MIN_VALUE && expL <= Integer.MAX_VALUE) {
        assertEquals((int) expL, parser.getIntValue());
    }
    assertNull(parser.nextToken());
