toBase64

public String toBase64(String source)

toASCII

public static String toASCII(String s)

Convert a string to ASCII. Non-ASCII characters will be escaped using the Unicode escape Java notation: "\\uxxx".

Parameters:

s - A string, which may include non ASCII characters.

Returns:

A string that contains only ASCII characters.

splitStringTokenCount

public static int splitStringTokenCount(String s,
                                        char delim)

Calculates the number of non-empty tokens in a string.

Parameters:

s -

delim -

Returns:

splitString

public static String[] splitString(String s,
                                   char delim)

Split string into non-empty tokens using the specified delimeter. This routine is supposed to be faster than String.split(String).

Parameters:

s - String to be split into tokens.

delim - Delimeter character.

Returns:

An array of tokens. Will never be null.
