Uses of PositionalElement in org.jppf.node.protocol

Classes in org.jppf.node.protocol with type parameters of type PositionalElement

Modifier and Type	Interface	Description
interface	PositionalElement<T extends PositionalElement<T>>	Interface representig an object that cn be accessed by its position in an ordered set.

Subinterfaces of PositionalElement in org.jppf.node.protocol

Modifier and Type	Interface	Description
interface	Task<T>	Interface for all tasks submitted to the execution server.

Classes in org.jppf.node.protocol that implement PositionalElement

Modifier and Type	Class	Description
class	AbstractTask<T>	Abstract superclass for all tasks submitted to the execution server.
class	CommandLineTask<T>	Instances of this class encapsulate the execution of an external process, program or shell script. 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.
class	JPPFExceptionResult	Instances of this class are used to signal that a task could not be sent back by the node to the server.
class	JPPFExceptionResultEx
class	JPPFTask	This class is kept for compatibility with existing user installations which make use of it, as we understand there are quite a few that still do.
class	ScriptedTask<T>	A task implementation which executes a script in a specified JSR 223 (javax.script APIs) script language.

Uses of PositionalElement in org.jppf.node.protocol.graph

Subinterfaces of PositionalElement in org.jppf.node.protocol.graph

Modifier and Type	Interface	Description
interface	TaskNode<T>	Interface for tasks that are part of a dependency graph of tasks within a job. Dependencies can be added using the dependsOn(Collection<TaskNode>) and dependsOn(TaskNode...) methods.

Classes in org.jppf.node.protocol.graph that implement PositionalElement

Modifier and Type	Class	Description
class	AbstractTaskNode<T>	Instances of this class represent tasks that are part of a dependency graph of tasks within a job. Dependencies can be added using the dependsOn(Collection<TaskNode>) and dependsOn(TaskNode...) methods.
static class	TaskGraph.Node	A node in the graph of the tasks in a job which represents a task and its dependants.

Methods in org.jppf.node.protocol.graph that return PositionalElement

Modifier and Type	Method	Description
PositionalElement<?>	TaskGraphInfo.getDependencyAt(int position)	Get the dependency at the specified position.

Methods in org.jppf.node.protocol.graph that return types with arguments of type PositionalElement

Modifier and Type	Method	Description
List<? extends PositionalElement<?>>	TaskGraphInfo.getDependencies()

Method parameters in org.jppf.node.protocol.graph with type arguments of type PositionalElement

Modifier and Type	Method	Description
void	TaskGraphInfo.setDependencies(List<? extends PositionalElement<?>> dependencies)	Set the actual dpeendencies, if available.
