ClassPath	A container for class path elements.
ClassPathElement	Instances of this class represent classpath elements that can be added dynamically to a JPPF class loader.

This task starts and external process using command line arguments, environment variables, and a list of input and/or output files to use or generated by the external process. This task also captures the standard and error output (i.e. equivalent to System.out and System.err) of the external process.
DataProvider	Instances of this class provide a way for tasks to share common data.

JPPFNodeConfigSpec	Instances of this class are set as job SLA attributes and describe the desired node configuration for a job.
JPPFTaskBundle	Instances of this class group tasks from the same client together, so they are sent to the same node, avoiding unnecessary transport overhead. The goal is to provide a performance enhancement through an adaptive bundling of tasks originating from the same client.
NotificationBundle.NotificationType	Possible types of notifications.
PersistenceSpec	This class defines whether a job should be persisted and the behavior of the persistence facility upon recovery.
