public enum TaskState
extends java.lang.Enum<TaskState>

The enumeration of the possible states of a Task.

Enum Constant Summary

ABORTED_INCOMPLETE
The Task terminated itself and is thus possibly incomplete.

ABORTED_ON_EXCEPTION
The Task was aborted by the Task Manager upon encountering an unhandled exception that propagated to the TaskManager.

CANCEL_REQUESTED
A cancellation has been requested for this task but the task has not acknowledged this request nor terminated itself.

CANCELLED
The task has terminated itself on a cancel request.

CANCELLING
The Task has acknowledged that it will be terminating itself.

COMPLETED
The task has completed normally.

CREATED
The initial state when a Task is constructed.

INTERRUPTED
The Thread was interrupted

PAUSE_REQUESTED
A Pause was requested but has not been acknowledged by the Task

PAUSED
The task has been Paused on request.

PAUSING
The task has acknowledged the Pause request but has not paused itself yet

RESERVED
reserved for internal use.

RUNNING
The task has been started.

SCHEDULED
The scheduled state means that the task manager has scheduled this task and any new tasks with resource locking requests will have to compete with this task.

Method Summary

static TaskState	valueOf(java.lang.String name) Returns the enum constant of this type with the specified name.
static TaskState[]	values() Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

CREATED

public static final TaskState CREATED

The initial state when a Task is constructed.

SCHEDULED

public static final TaskState SCHEDULED

The scheduled state means that the task manager has scheduled this task and any new tasks with resource locking requests will have to compete with this task. The scheduled state may be skipped, going directly to running state.

RUNNING

public static final TaskState RUNNING

The task has been started. Whether the thread is running or not depends on the state of the Thread itself.

COMPLETED

public static final TaskState COMPLETED

The task has completed normally.

CANCEL_REQUESTED

public static final TaskState CANCEL_REQUESTED

A cancellation has been requested for this task but the task has not acknowledged this request nor terminated itself.

CANCELLING

public static final TaskState CANCELLING

The Task has acknowledged that it will be terminating itself.

CANCELLED

public static final TaskState CANCELLED

The task has terminated itself on a cancel request.

ABORTED_ON_EXCEPTION

public static final TaskState ABORTED_ON_EXCEPTION

The Task was aborted by the Task Manager upon encountering an unhandled exception that propagated to the TaskManager.

INTERRUPTED

public static final TaskState INTERRUPTED

The Thread was interrupted

PAUSE_REQUESTED

public static final TaskState PAUSE_REQUESTED

A Pause was requested but has not been acknowledged by the Task

PAUSING

public static final TaskState PAUSING

The task has acknowledged the Pause request but has not paused itself yet

PAUSED

public static final TaskState PAUSED

The task has been Paused on request.

RESERVED

Method Detail

values

public static TaskState[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (TaskState c : TaskState.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static TaskState valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null
