CronTriggerBuilder (taskplanner)

java.lang.Object
- com.inet.taskplanner.server.api.trigger.CronTriggerBuilder

```
public class CronTriggerBuilder
extends java.lang.Object
```
Use this to construct a TriggerDefinition for a cron Trigger.
A cron trigger only needs one expression to be configured. The expression has the following syntax:
(minute) (hour) (dayOfMonth) (month) (dayOfWeek) (year)
Each value is separated by a space, the year value can be omitted. Only one of dayOfMonth and dayOfWeek can be specified, the other one must be '?'. It follows the QUARTZ syntax without the seconds value! See http://www.quartz-scheduler.org/documentation/quartz-2.x/tutorials/crontrigger.html for more detais on the syntax.
Example usage:
```
 
 
  TaskDefinition task = new TaskDefinition("mytask");
  TriggerDefinition cron = CronTriggerBuilder.create("0 18 1 * ?");
  task.addTrigger(cron);
  // ...add jobs and Actions...
  TaskPlanner.getInstance().addTask( task );
 
 
```
