Miscellaneous String utility methods.

Mainly for internal use within the framework; consider Jakarta's Commons Lang for a more comprehensive suite of String utilities.

This class delivers some simple functionality that should really be provided by the core Java String and StringBuffer classes, such as the ability to replace(java.lang.String, java.lang.String, java.lang.String) all occurrences of a given substring in a target string. It also provides easy-to-use methods to convert between delimited strings, such as CSV strings, and collections and arrays.

 delimiters, consider using delimitedListToStringArray


Parameters:
str - the String to tokenize
delimiters - the delimiter characters, assembled as String
 (each of those characters is individually considered as delimiter).
Returns:
an array of the tokens
See Also:
StringTokenizer, 
String.trim(),

Tokenize the given String into a String array via a StringTokenizer.
 The given delimiters string is supposed to consist of any number of
 delimiter characters. Each of those characters can be used to separate
 tokens. A delimiter is always a single character; for multi-character
 delimiters, consider using delimitedListToStringArray


Parameters:
str - the String to tokenize
delimiters - the delimiter characters, assembled as String
 (each of those characters is individually considered as delimiter)
trimTokens - trim the tokens via String's trim
ignoreEmptyTokens - omit empty tokens from the result array
 (only applies to tokens that are empty after trimming; StringTokenizer
 will not consider subsequent delimiters as token in the first place).

Take a String which is a delimited list and convert it to a String array.
 A single delimiter can consists of more than one character: It will still
 be considered as single delimiter string, rather than as bunch of potential
 delimiter characters - in contrast to tokenizeToStringArray.


Parameters:
str - the input String
delimiter - the delimiter between elements (this is a single delimiter,
 rather than a bunch individual delimiter characters)
Returns:
an array of the tokens in the list
See Also:
tokenizeToStringArray(java.lang.String, java.lang.String)

Take a String which is a delimited list and convert it to a String array.
 A single delimiter can consists of more than one character: It will still
 be considered as single delimiter string, rather than as bunch of potential
 delimiter characters - in contrast to tokenizeToStringArray.


Parameters:
str - the input String
delimiter - the delimiter between elements (this is a single delimiter,
 rather than a bunch individual delimiter characters)
charsToDelete - a set of characters to delete. Useful for deleting unwanted
 line breaks: e.g. "\r\n\f" will delete all new lines and line feeds in a String.
