Constructor Detail

CmsRegexValidator

public CmsRegexValidator(java.lang.String regex,
                         java.lang.String message,
                         boolean alwaysAllowEmpty)

Creates a new regex-based validator. The regular expression passed as a parameter is used to match complete strings, not parts of strings. For example, a regex of "AAA" will only match the string "AAA", and not "BAAA". If the regex starts with an exclamation mark ("!"), the match will be inverted, i.e. only strings that don't match the rest of the regular expression will be interpreted as valid.

Parameters:

regex - a regular expression

message - an error message

alwaysAllowEmpty - if true, the validation will always allow the empty string
