Usage

From source file:edu.kit.trufflehog.model.network.MacAddress.java

public MacAddress(long address) throws InvalidMACAddress {

    this.address = address;

    if (this.address > 0xFFFFFFFFFFFFL || this.address < 0) {
        throw new InvalidMACAddress(address);
    }//from  www  . j a v  a 2s .co  m

    hashcode = (new Long(address)).hashCode();
    // transform to byte array
    final byte[] extractedBytes = ByteBuffer.allocate(8).putLong(address).array();
    bytes = Arrays.copyOfRange(extractedBytes, 2, 8);

    // set multicast bit
    isMulticast = (bytes[0] & 1) == 1;

    // set string representation
    final List<Byte> bytes = Arrays.asList(ArrayUtils.toObject(toByteArray()));
    addressString = bytes.stream().map(b -> String.format("%02x", b)).collect(Collectors.joining(":"));
