Class DateSelector

java.lang.Object
  dsto.dfc.swing.text.selection.DateSelector

All Implemented Interfaces:

Convertable, PatternSelector, Selector, Serializable

public class DateSelector
extends Object
implements PatternSelector, Serializable

A basic selector for java.util.Date objects. Currently allows "*" or an ISO date (yyyy-mm-dd hh:mm:ss timezone or shortened versions of the same) as a selector. Multiple dates can OR'd with ",". Ranges (inclusive) can be specified using syntax like "date1 > date2".

Examples:

   "*"
   "2001"
   "2001-01-02"
   "2001-01-02 10:14:01" (uses local timezone)
   "2001-01-02 10:14:01 UTC+9:30"
   "2001>2002,2004>2005"
