Examples of org.quartz.simpl.RAMJobStore

org.quartz.simpl.RAMJobStore

This class implements a {@link org.quartz.spi.JobStore} that utilizes RAM as its storage device.

As you should know, the ramification of this is that access is extrememly fast, but the data is completely volatile - therefore this JobStore should not be used if true persistence between program shutdowns is required.
