This can be useful for reports and GUI + * presentations when you need to display data exactly as it appears in Excel. Supported formats include currency, SSN, + * percentages, decimals, dates, phone numbers, zip codes, etc. + *

+ * Internally, formats will be implemented using subclasses of {@link Format} such as {@link DecimalFormat} and + * {@link java.text.SimpleDateFormat}. Therefore the formats used by this class must obey the same pattern rules as + * these Format subclasses. This means that only legal number pattern characters ("0", "#", ".", "," etc.) may appear in + * number formats. Other characters can be inserted before or after the number pattern to form a + * prefix or suffix. + *

+ *

+ * For example the Excel pattern "$#,##0.00 "USD"_);($#,##0.00 "USD")" + * will be correctly formatted as "$1,000.00 USD" or "($1,000.00 USD)". However the pattern + * "00-00-00" is incorrectly formatted by DecimalFormat as "000000--". For Excel formats that are not + * compatible with DecimalFormat, you can provide your own custom {@link Format} implementation via + * DataFormatter.addFormat(String,Format). The following custom formats are already provided by this class: + *

+ * + * 
+ * 
  • SSN "000-00-0000"
    • 
+ *     
  • Phone Number "(###) ###-####"
    • 
+ *     
  • Zip plus 4 "00000-0000"
    • 
+ * 

+ *
+ *

+ * If the Excel format pattern cannot be parsed successfully, then a default format will be used. The default number + * format will mimic the Excel General format: "#" for whole numbers and "#.##########" for decimal numbers. You can + * override the default format pattern with + * DataFormatter.setDefaultNumberFormat(Format). Note: the default format will only be used when a Format + * cannot be created from the cell's data format string. + * + *

+ * Note that by default formatted numeric values are trimmed. Excel formats can contain spacers and padding and the + * default behavior is to strip them off. + *

+ *

+ * Example: + *

+ *

+ * Consider a numeric cell with a value 12.343 and format "##.##_ ". The trailing underscore + * and space ("_ ") in the format adds a space to the end and Excel formats this cell as "12.34 ", but + * DataFormatter trims the formatted value and returns "12.34". + *

+ * You can enable spaces by passing the emulateCSV=true flag in the DateFormatter cosntructor. + * If set to true, then the output tries to conform to what you get when you take an xls or xlsx in Excel and Save As + * CSV file: + *
    + *
  • returned values are not trimmed
    • + *
  • Invalid dates are formatted as 255 pound signs ("#")
    • + *
  • simulate Excel's handling of a format string of all # when the value is 0. Excel will output "", + * DataFormatter will output "0". + *
+ *

+ * Some formats are automatically "localized" by Excel, eg show as mm/dd/yyyy when loaded in Excel in some Locales but + * as dd/mm/yyyy in others. These are always returned in the "default" (US) format, as stored in the file. Some format + * strings request an alternate locale, eg [$-809]d/m/yy h:mm AM/PM which explicitly requests UK locale. + * These locale directives are (currently) ignored. You can use {@link DateFormatConverter} to do some of this + * localisation if you need it. + */ +public class DataFormatter1 implements Observer { + private static final String defaultFractionWholePartFormat = "#"; + private static final String defaultFractionFractionPartFormat = "#/##"; + /** Pattern to find a number format: "0" or "#" */ + private static final Pattern numPattern = Pattern.compile("[0#]+"); + + /** Pattern to find days of week as text "ddd...." */ + private static final Pattern daysAsText = Pattern.compile("([d]{3,})", Pattern.CASE_INSENSITIVE); + + /** Pattern to find "AM/PM" marker */ + private static final Pattern amPmPattern = Pattern.compile("((A|P)[M/P]*)", Pattern.CASE_INSENSITIVE); + + /** Pattern to find formats with condition ranges e.g. [>=100] */ + private static final Pattern rangeConditionalPattern = + Pattern.compile(".*\\[\\s*(>|>=|<|<=|=)\\s*[0-9]*\\.*[0-9].*"); + + /** + * A regex to find locale patterns like [$$-1009] and [$?-452].
