Method Detail

standardSplit

public static String[] standardSplit(String input)

Splits apart the input String on any whitespace and/or commas. Leading and trailing whitespace are ignored. If a null String is provided as input a zero length array will be returned.

Parameters:

input - the String to split apart

Returns:

an array of substrings of the input String based on the split

combineParts

public static String combineParts(Object... messageParts)

Combines a bunch of objects into a single String. Array contents get converted nicely.

urlEncode

public static String urlEncode(String value)

URL-encodes value using the UTF-8 charset. Using this method eliminates the need for a try/catch since UTF-8 is guaranteed to exist.

See Also:

URLEncoder.encode(String, String)

urlDecode

public static String urlDecode(String value)

URL-decodes value using the UTF-8 charset. Using this method eliminates the need for a try/catch since UTF-8 is guaranteed to exist.

See Also:

URLDecoder.decode(String, String)

uriFragmentEncode

public static String uriFragmentEncode(String value)

Encode a URI fragment as required by RFC 3986. The fragment is allowed to contain a different set of characters than other parts of the URI, and characters that are allowed in the fragment must not be encoded.

Parameters:

value - The string to encode

Returns:

The encoded string

trimFragment

public static String trimFragment(String url)

Return the specified URL or path string with the fragment part removed. If the string does not contain a fragment then return the string unchanged.

Parameters:

url - The URL or path

Returns:

The URL or path without the fragment
