Class L10nDecimalFormat

java.lang.Object

java.text.Format

de.ipcon.tools.L10nDecimalFormat

All Implemented Interfaces:

L10nFormatI, java.io.Serializable, java.lang.Cloneable

public class L10nDecimalFormat
extends java.text.Format
implements L10nFormatI

This class just adds a getPattern-Method so that we can extract the original pattern again out of it. The toPattern method is just way too slow for that (and this is for speed, isn't it?) And, as we are here already, we can implement some nice things, too:

• functionality for getting default numbering schemes like CURRENCY, PERCENT, NUMBER and INTEGER
• setting explicit locales with prepending locales like [en_US] infront of formats
• automatically enable BigDecimal parsing
• setting inline factors like /100 or *1000 into formats to better support mks in domain values

[s: 0.##m | /1000 0.##km] -- choose by length of string [p: *100 0cm | 0m | /1000 0km] -- choose by highest precision -- not yet implemented [r: 0..200 *100 cm | 200..1999 m | /1000 0km ] -- by explicit range -- neither implemented
