Class Date

java.lang.Object
  net.sf.oness.common.all.BaseObject
      net.sf.oness.common.model.temporal.Date

All Implemented Interfaces:

java.lang.Cloneable, java.lang.Comparable, java.io.Serializable

public class Date

extends net.sf.oness.common.all.BaseObject

implements java.lang.Comparable

Wrapper around a Calendar object truncated to the field specified (by default SECOND) using DateUtils.truncate(Calendar, int).

The MIN_VALUE and MAX_VALUE fields represent negative and positive infinity respectively, the implementation doesn't use Calendar.getMinimum or Calendar.getMaximum because the underlying database may not accept the range of values available in Calendar
