Class JobBuilder

java.lang.Object

org.quartz.JobBuilder

public class JobBuilder
extends Object

JobBuilder is used to instantiate JobDetails.

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 withIdentity(..) a job 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);

Method Detail

newJob

public static JobBuilder newJob()

Create a JobBuilder with which to define a JobDetail.

Returns:

a new JobBuilder

newJob

public static JobBuilder newJob(Class<? extends Job> jobClass)

Create a JobBuilder with which to define a JobDetail, and set the class name of the Job to be executed.

Returns:

a new JobBuilder

build

public JobDetail build()

Produce the JobDetail instance defined by this JobBuilder.

Returns:

the defined JobDetail.

withIdentity

public JobBuilder withIdentity(String name)

Use a JobKey with the given name and default group to identify the JobDetail.

If none of the 'withIdentity' methods are set on the JobBuilder, then a random, unique JobKey will be generated.

Parameters:

name - the name element for the Job's JobKey

Returns:

the updated JobBuilder

See Also:

JobKey, JobDetail.getKey()

withIdentity

public JobBuilder withIdentity(String name,
                               String group)

Use a JobKey with the given name and group to identify the JobDetail.

If none of the 'withIdentity' methods are set on the JobBuilder, then a random, unique JobKey will be generated.

Parameters:

name - the name element for the Job's JobKey

group - the group element for the Job's JobKey

Returns:

the updated JobBuilder

See Also:

JobKey, JobDetail.getKey()

withIdentity

public JobBuilder withIdentity(JobKey jobKey)

Use a JobKey to identify the JobDetail.

If none of the 'withIdentity' methods are set on the JobBuilder, then a random, unique JobKey will be generated.

Parameters:

jobKey - the Job's JobKey

Returns:

the updated JobBuilder

See Also:

JobKey, JobDetail.getKey()

withDescription

public JobBuilder withDescription(String jobDescription)

Set the given (human-meaningful) description of the Job.

Parameters:

jobDescription - the description for the Job

Returns:

the updated JobBuilder

See Also:

JobDetail.getDescription()

ofType

public JobBuilder ofType(Class<? extends Job> jobClazz)

Set the class which will be instantiated and executed when a Trigger fires that is associated with this JobDetail.

Parameters:

jobClazz - a class implementing the Job interface.

Returns:
