Method Summary

static java.lang.String	decodeURLEncoding(java.lang.String s) Takes a URL-encoded string and decodes it.
static java.lang.String	encodeURL(java.lang.String s) Performs URL encoding of a string
static java.lang.String	generateUUID() Type 1 (time-based) Pure-Java UUID Generator This has the advantage of not using SecureRandom (being time-based) and is therefore fast.
static java.lang.String	replace(java.lang.String inString, java.lang.String oldPattern, java.lang.String newPattern) Replace all occurences of a substring within a string with another string.
static java.lang.String[]	split(java.lang.String splitstring, java.lang.String splitchar) Splits a string by a particular char and returns an array of strings.

Method Detail

generateUUID

public static java.lang.String generateUUID()

Type 1 (time-based) Pure-Java UUID Generator This has the advantage of not using SecureRandom (being time-based) and is therefore fast. Note that it uses the hostname and a some random entropy to construct a node rather than the ethernet MAC address (to keep it pure java). Despite this limitation, it should still produce very good, unique UUIDs since the mix of hostname/randomness and UTC since the epoch down to the millisecond should be good enough for most applications. The output format is a UUID URN according to the IETF draft, which you can find here: http://www.ietf.org/internet-drafts/draft-mealling-uuid-urn-03.txt

split

public static java.lang.String[] split(java.lang.String splitstring,
                                       java.lang.String splitchar)

Splits a string by a particular char and returns an array of strings. If there are no occurrences of the split char, the original string is returned in an array of 1 item.

Parameters:

splitstring - The string to be split

splitchar - The char to split on

Returns:

An array of strings

replace

public static java.lang.String replace(java.lang.String inString,
                                       java.lang.String oldPattern,
                                       java.lang.String newPattern)

Replace all occurences of a substring within a string with another string.

Parameters:

inString - String to examine

oldPattern - String to replace

newPattern - String to insert

Returns:

a String with the replacements

Parameters:

s - A URL encoded string

Returns:

The decoded string

encodeURL

public static java.lang.String encodeURL(java.lang.String s)
