Class Time

java.lang.Object
  org.nakedobjects.applib.value.Magnitude
      org.nakedobjects.applib.value.Time

All Implemented Interfaces:

Serializable

public class Time
extends Magnitude

Value object representing a time value.

TODO: other methods to implement:

• comparison methods
• sameHourAs() hour ==hour sameMinuteAs() minutes = minutes sameTimeAs(hour, min) hour == hour & minutes == minutes
• withinNextTimePeriod(int hours, int minutes); withinTimePeriod(Date d, int hours, int minutes)
• withinPreviousTimePeriod(int hours, int minutes); d.hour >= this.hour >= d.hour + hours & d.minutes >= this.minutes >= d.minutes + minutes
