                                                 java.util.regex.Pattern pattern,
                                                 java.lang.String replacement,
                                                 java.lang.String missingMatchErrorMessage)
                                          throws TagneticBadDataException

TagneticBadDataException

escapeRegExpSensitiveCharacters

public static java.lang.String escapeRegExpSensitiveCharacters(java.lang.String value)

safeReplaceAll

public static java.lang.String safeReplaceAll(java.lang.String input,
                                              java.lang.String regexp,
                                              java.lang.String replacement)

This method differs from the String.replaceAll method in that it "escapes" the $ and \ characters in the replacement string. Those are special characters used for regexp groups, but normally in tagnetic parsing, we don't use those characters for that purpose.
