方法详细资料

addToSNIServerNameList

static List<SNIServerName> addToSNIServerNameList(List<SNIServerName> serverNames,
                                                  String hostname)

Puts hostname into the serverNames list.

If the serverNames does not look like a legal FQDN, it will not be put into the returned list.

Note that the returned list does not allow duplicated name type.

返回:

a list of SNIServerName

rawToSNIHostName

private static SNIHostName rawToSNIHostName(String hostname)

Converts string hostname to SNIHostName.

Note that to check whether a hostname is a valid domain name, we cannot use the hostname resolved from name services. For virtual hosting, multiple hostnames may be bound to the same IP address, so the hostname resolved from name services is not always reliable.

参数:

hostname - the raw hostname

返回:

an instance of SNIHostName, or null if the hostname does not look like a FQDN

getBooleanProperty

static boolean getBooleanProperty(String propName,
                                  boolean defaultValue)

Return the value of the boolean System property propName. Note use of privileged action. Do NOT make accessible to applications.

indent

static String indent(String source)

indent

static String indent(String source,
                     String prefix)

toHexString

static String toHexString(byte b)

byte16HexString

static String byte16HexString(int id)

toHexString

static String toHexString(byte[] bytes)

toHexString

static String toHexString(long lv)

toByteArray

static byte[] toByteArray(BigInteger bi)

Utility method to convert a BigInteger to a byte array in unsigned format as needed in the handshake messages. BigInteger uses 2's complement format, i.e. it prepends an extra zero if the MSB is set. We remove that.

rangeCheck

private static void rangeCheck(int arrayLength,
                               int fromIndex,
                               int toIndex)

Checks that fromIndex and toIndex are in the range and throws an exception if they aren't.
