public MCast()

Method Detail

toCurrencyString

public static String toCurrencyString(double _in)

Will round the value mathematically and return every time a comma as separator and two digits after comma.

Parameters:

_in -

Returns:

toDate

public static Date toDate(String _in,
          Date _def)

Try to parse a String and return the equivalent Date object. The string should contain a iso date string like "yyyy-mm-dd" syntax: "yyyy-mm-dd[[ HH:MM:SS].XXX]" where XXX is Millisecond. Milliseconds are ignored. For the date part there are alternative syntax: "dd.mm.yyyy" or "mm/dd/yyyy".

If the time is not in the string, it will be set to "00:00:00". It is possible to leave year, in this case it will be replaced with the actuall year. If you leave month, it will be replaced with the actuall month.

Parameters:

_in - Iso DateTime

Returns:

In all cases an Date() object. Is getTime() is 0, it occurs an error: ACast.toDate( in ).getTime == 0.

toCalendar

public static Calendar toCalendar(Date _in)

toCalendar

public static Calendar toCalendar(Date _in,
                  TimeZone tz,
