Class TimePeriodOptionHandler

java.lang.Object
  org.kohsuke.args4j.spi.OptionHandler<T>
      org.kohsuke.args4j.spi.OneArgumentOptionHandler<Long>
          org.cumulus4j.keymanager.cli.TimePeriodOptionHandler

public class TimePeriodOptionHandler
extends org.kohsuke.args4j.spi.OneArgumentOptionHandler<Long>

Option handler implementation to interprete a time period (e.g. "5 minutes".

The time period is specified in the command line by writing a number directly followed (no space!) by a unit. For example 5 minutes could be written as "5min" or "300s" (300 seconds are 5 minutes).

This handler can be chosen for every long property using the Option annotation like this:

 @Option(name="-myArg", handler=TimePeriodOptionHandler.class)
 private long myArg;
 

The long property will be set to the milliseconds value. For example, if the command line user passes "5min", the long value will be 300000 (5 min * 60 s * 1000 ms).
