Constructor Detail

StringNormalizer.RegexNormalizerRule

public StringNormalizer.RegexNormalizerRule(String... patterns)

Create a new regular expression rule using a series of pattern/replacement pairs. Each pattern/replacement will be applied globally (all matches that can be found). If multiple patterns are given, they will be applied in the order given. Use this form:

 myRule = new RegexNormalizerRule(
     "pattern1", "replacement1",
     "pattern2", "replacement2",
     ... // As many as you want
 );
 

Parameters:

patterns - a series of regular expression pattern/replacement pairs (there must be an even number!)

StringNormalizer.RegexNormalizerRule

public StringNormalizer.RegexNormalizerRule(boolean everywhere,
                                            String... patterns)

Create a new regular expression rule using a series of pattern/replacement pairs.

Parameters:

everywhere - True if all pattern/replacements should be applied globally (for every match), or false if the replacements should only be applied to the first match for each pattern.

patterns - a series of regular expression pattern/replacement pairs (there must be an even number!)
