Method Detail

safeReplaceAll

public static String safeReplaceAll(String text,
                                    String regex,
                                    String replacement)

Workaround for standard regex replacement method if string contains unallowed chars.

For instance the String.replaceAll() method throws an exception if the string to be replaced contains a dollar character ($) since this is interpreted as group. Make sure that no %DOLLAR% substring is included since this is used ad intermediary.

This method should always be used if the replacement string may contain illegal group references (dollar characters: $).

Parameters:

text - The text to be replaced

regex - The regular expressions to be replaced (all occurrences)

replacement - The replacements for the regular expressions, may contain unallowed chars

Returns:

The text after replacement

Throws:

NullPointerException - If text, regex, or replacement is null

java.util.regex.PatternSyntaxException - If regex is invalid

                                   int spaces,
                                   Character framechar)

Converts the given table data to aligned columns with a certain space.

Parameters:

array - The array, toString() is called

spaces - The number of space characters between two columns

framechar - Character to use for the header and footer lines (optional)

Returns:

The aligned table

Throws:

NullPointerException - If array is null
