splitAndTrim

public static String[] splitAndTrim(String string,
                    String delim)

Like StringUtils.split(String, String), but additionally trims whitespace from the result tokens.

hexStringToByteArray

public static byte[] hexStringToByteArray(String hex)

Convert a hexadecimal string into its byte representation.

Parameters:

hex - The hexadecimal string.

Returns:

The converted bytes or null if the hex String is null.

repeat

            int len)

Like StringUtils.repeat(String, int) but with a single character as argument.

toHexString

public static String toHexString(byte[] bytes)

See Also:

toHexString(byte[])

toHexString

public static String toHexString(byte[] bytes,
                 boolean uppercase)

Convert a byte array to a hexadecimal string.

Parameters:

bytes - The bytes to format.

uppercase - When true creates uppercase hex characters instead of lowercase (the default).

Returns:

A hexadecimal representation of the specified bytes.

match

public static String match(Pattern pattern,
           String value,
           int matchIndex)
                    throws IllegalArgumentException

Matches the given value to the given pattern. Then returns the group at matchIndex.

Parameters:

pattern - the pattern to use as regexp

value - the value to evaluate
