Examples of org.apache.wicket.util.time.Duration

org.apache.wicket.util.time.Duration
A Duration is an immutable length of time stored as a number of milliseconds. Various factory and conversion methods are available for convenience.
These static factory methods allow easy construction of value objects using either long values like seconds(2034) or hours(3):
- Duration.milliseconds(long)
- Duration.seconds(int)
- Duration.minutes(int)
- Duration.hours(int)
- Duration.days(int)
...or double-precision floating point values like days(3.2):
- Duration.milliseconds(double)
- Duration.seconds(double)
- Duration.minutes(double)
- Duration.hours(double)
- Duration.days(double)
In the case of milliseconds(double), the value will be rounded off to the nearest integral millisecond using Math.round().
The precise number of milliseconds represented by a Duration object can be retrieved by calling the getMilliseconds method. The value of a Duration object in a given unit like days or hours can be retrieved by calling one of the following unit methods, each of which returns a double-precision floating point number:
- seconds()
- minutes()
- hours()
- days()
Values can be added and subtracted using the add(Duration) and subtract(Duration) methods, each of which returns a new immutable Duration object.
String values can be converted to Duration objects using the static valueOf factory methods. The String format is the opposite of the one created by toString(), which converts a Duration object to a readable form, such as "3.2 hours" or "32.5 minutes". Valid units are: milliseconds, seconds, minutes hours and days. Correct English plural forms are used in creating String values and are parsed as well. The Locale is respected and "," will be used instead of "." in the Eurozone.
The benchmark method will "benchmark" a Runnable or an {@link ICode} implementingobject, returning a Duration object that represents the amount of time elapsed in running the code.
Finally, the sleep method will sleep for the value of a Duration. @author Jonathan Locke @since 1.2.6
