Class TriggerBuilder<T extends Trigger>

  • public class TriggerBuilder<T extends Trigger>
extends java.lang.Object
    TriggerBuilder is used to instantiate Triggers.

    The builder will always try to keep itself in a valid state, with reasonable defaults set for calling build() at any point. For instance if you do not invoke withSchedule(..) method, a default schedule of firing once immediately will be used. As another example, if you do not invoked withIdentity(..) a trigger name will be generated for you.

    Quartz provides a builder-style API for constructing scheduling-related entities via a Domain-Specific Language (DSL). The DSL can best be utilized through the usage of static imports of the methods on the classes TriggerBuilder, JobBuilder, DateBuilder, JobKey, TriggerKey and the various ScheduleBuilder implementations.

    Client code can then use the DSL to write code such as this:

             JobDetail job = newJob(MyJob.class)
             .withIdentity("myJob")
             .build();
             
         Trigger trigger = newTrigger() 
             .withIdentity(triggerKey("myTrigger", "myTriggerGroup"))
             .withSchedule(simpleSchedule()
                 .withIntervalInHours(1)
                 .repeatForever())
             .startAt(futureDate(10, MINUTES))
             .build();
         
         scheduler.scheduleJob(job, trigger);
