org.quartz

The main package of Quartz, containing the client-side interfaces.

An interface to be implemented by objects that define spaces of time during which an associated Trigger may fire.

An exception that is thrown to indicate that there has been a critical failure within the scheduler's core services (such as loss of database connectivity).

A concrete Trigger that is used to fire a org.quartz.JobDetail at given moments in time, defined with Unix 'cron-like' definitions.

The interface to be implemented by Job s that provide a mechanism for having their execution interrupted.

The interface to be implemented by classes which represent a 'job' to be performed.

Holds state information for Job instances.

JobDataMap instances are stored once when the Job is added to a scheduler.

Conveys the detail properties of a given Job instance.

Quartz does not store an actual instance of a Job class, but instead allows you to define an instance of one, through the use of a JobDetail.

Jobs have a name and group associated with them, which should uniquely identify them within a single Scheduler .

Triggers are the 'mechanism' by which Jobs are scheduled.

A context bundle containing handles to various environment information, that is given to a org.quartz.JobDetail instance as it is executed, and to a Trigger instance after the execution completes.

The JobDataMap found on this object (via the getMergedJobDataMap() method) serves as a convenience - it is a merge of the JobDataMap found on the JobDetail and the one found on the Trigger, with the value in the latter overriding any same-named values in the former. It is thus considered a 'best practice' that the execute code of a Job retrieve data from the JobDataMap found on this object NOTE: Do not expect value 'set' into this JobDataMap to somehow be set back onto a StatefulJob's own JobDataMap.

JobExecutionContext s are also returned from the Scheduler.getCurrentlyExecutingJobs() method.

An exception that can be thrown by a org.quartz.Job to indicate to the Quartz Scheduler that an error occured while executing, and whether or not the Job requests to be re-fired immediately (using the same JobExecutionContext , or whether it wants to be unscheduled.

The interface to be implemented by classes that want to be informed when a org.quartz.JobDetail executes.

An exception that is thrown to indicate that there has been a failure in the scheduler's underlying persistence mechanism.

An exception that is thrown to indicate that an attempt to store a new object (i.e.

This is the main interface of a Quartz Scheduler.

A Scheduler maintains a registery of org.quartz.JobDetail s and Trigger s.

An exception that is thrown to indicate that there is a misconfiguration of the SchedulerFactory- or one of the components it configures.

Holds context/environment data that can be made available to Jobs as they are executed.

Base class for exceptions thrown by the Quartz Scheduler .

Provides a mechanism for obtaining client-usable handles to Scheduler instances.

The interface to be implemented by classes that want to be informed of major Scheduler events.

Describes the settings and capabilities of a given Scheduler instance.

A concrete Trigger that is used to fire a org.quartz.JobDetail at a given moment in time, and optionally repeated at a specified interval.

A marker interface for org.quartz.JobDetail s that wish to have their state maintained between executions.

StatefulJob instances follow slightly different rules from regular Job instances.

The base abstract class to be extended by all Triggers.

Triggers s have a name and group associated with them, which should uniquely identify them within a single Scheduler .

Triggers are the 'mechanism' by which Job s are scheduled.

The interface to be implemented by classes that want to be informed when a Trigger fires.

Convenience and utility methods for simplifying the construction and configuration of Trigger s.

An exception that is thrown to indicate that a call to InterruptableJob.interrupt() failed without interrupting the Job.
