public class FwUtility

extends java.lang.Object

I maintain a bunch of static methods that are sometimes useful but that are difficult to organize somewhere else. Basically I put these methods here because I didn't know where else to put them. In general, this class should NOT reference other Fw classes. It may be reasonable to reference other utility classes but I should not reference the domain or other application specific packages.

Method Detail

lastDayOf

public static int lastDayOf(int m,
                            int y)

arrayToVector

public static java.util.Vector arrayToVector(java.lang.Object[] arr)

GetAvailableLocale

public static java.util.Locale GetAvailableLocale(java.util.Vector localeVector,
                                                  java.util.Locale locale)

vectorToArray

public static java.lang.Object[] vectorToArray(java.util.Vector v)

classNamed

public static java.lang.Class classNamed(java.lang.String name)

printStackTrace

public static void printStackTrace()

redirectOutputTo

public static void redirectOutputTo(java.lang.String os,
                                    java.lang.String es,
                                    boolean append,
                                    boolean header)

I redirect the System.out and System.err streams to some file. If the file name is null then I use the standard out and standard error streams which normally display on the screen. If directed to a named file then I may optionally append to that file instead of overwriting it.
