Description

Interface Summary

JPPFDistributedJob	Common interface for client-side jobs (see JPPFJob and server-side jobs (see JPPFTaskBundle).
JPPFTaskListener	Listener interface for receiving notifications of tasks events.
Location<T>	Abstraction of a block of data no matter how its actual location is referred to.
LocationEventListener	Listener for events occurring with Location objects.
TaskCompletionListener	Listener providing a callback to invoke when a task's execution has completed.

Class Summary

AbstractLocation<T>	Instances of this class represent the location of an artifact, generally a file or the data found at a url.
BundleWrapper	This class wraps a task bundle to express it in terms of DataLocation.
CommandLineTask	Instances of this class encapsulate the execution of an external process, program or shell script.
FileLocation	Wrapper fro manipulating a file.
JPPFExceptionResult	Instances of this class are used to signal that a task could not be sent back by the node to the server.
JPPFJobMetadata	Instances of this class hold metadata about a job, that can be used from a load-balancer, to adapt the load balancing to the computational weight of the job and/or the contained tasks.
JPPFJobSLA	This class represents the Service Level Agreement Between a JPPF job and a server.
JPPFTask	Abstract superclass for all tasks submitted to the execution server.
JPPFTaskBundle	Instances of this class group tasks from the same client together, so they are sent to the same node, avoiding unnecessary transport overhead.
JPPFTaskEvent	Instances of this class represent events sent by a JPPF task.
LocationEvent	Instances of this class represent events occurring when performing I/O operations between Location instances.
MemoryLocation	Wrapper fro manipulating a file.
URLLocation	Wrapper for manipulating data from a URL.

Enum Summary

BundleParameter	Constants used when a client sends an admin command to a server.
JPPFTaskBundle.State	Type safe enumeration for the values of the bundle state.

Annotation Types Summary

JPPFRunnable

Annotation to determine which method in a class is the task's main method.
