Examples with SchedulerRepository org.quartz.impl.SchedulerRepository used on opensource projects

Example 1 with SchedulerRepository

use of org.quartz.impl.SchedulerRepository in project spring-framework by spring-projects.

the class SchedulerFactoryBean method createScheduler.

/**
	 * Create the Scheduler instance for the given factory and scheduler name.
	 * Called by {@link #afterPropertiesSet}.
	 * <p>The default implementation invokes SchedulerFactory's {@code getScheduler}
	 * method. Can be overridden for custom Scheduler creation.
	 * @param schedulerFactory the factory to create the Scheduler with
	 * @param schedulerName the name of the scheduler to create
	 * @return the Scheduler instance
	 * @throws SchedulerException if thrown by Quartz methods
	 * @see #afterPropertiesSet
	 * @see org.quartz.SchedulerFactory#getScheduler
