示例1: parseIPv6
import sun.security.util.BitArray; //导入方法依赖的package包/类
private void parseIPv6(String name) throws IOException {
int slashNdx = name.indexOf('/');
if (slashNdx == -1) {
address = InetAddress.getByName(name).getAddress();
} else {
address = new byte[32];
byte[] base = InetAddress.getByName
(name.substring(0, slashNdx)).getAddress();
System.arraycopy(base, 0, address, 0, 16);
// append a mask corresponding to the num of prefix bits specified
int prefixLen = Integer.parseInt(name.substring(slashNdx+1));
if (prefixLen > 128)
throw new IOException("IPv6Address prefix is longer than 128");
// create new bit array initialized to zeros
BitArray bitArray = new BitArray(MASKSIZE * 8);
// set all most significant bits up to prefix length
for (int i = 0; i < prefixLen; i++)
bitArray.set(i, true);
byte[] maskArray = bitArray.toByteArray();
// copy mask bytes into mask portion of address
for (int i = 0; i < MASKSIZE; i++)
address[MASKSIZE+i] = maskArray[i];
}
