Enum Class StructuredTaskScope.Subtask.State

java.lang.Object

java.lang.Enum<StructuredTaskScope.Subtask.State^PREVIEW>

java.util.concurrent.StructuredTaskScope.Subtask.State

All Implemented Interfaces:: Serializable, Comparable<StructuredTaskScope.Subtask.State^PREVIEW>, Constable

Enclosing interface:: StructuredTaskScope.Subtask^PREVIEW<T>

public static enum StructuredTaskScope.Subtask.State extends Enum<StructuredTaskScope.Subtask.StatePREVIEW>

State is a preview API of the Java platform.

Programs can only use State when preview features are enabled.

Preview features may be removed in a future release, or upgraded to permanent features of the Java platform.

Represents the state of a Subtask^PREVIEW.

Nested classes/interfaces declared in class Enum

Enum.EnumDesc<E>

Modifier and Type	Class	Description
`static final class`	`Enum.EnumDesc<E extends Enum<E>>`	A nominal descriptor for an `enum` constant.

Enum Constant Summary

Enum Constant	Description
`FAILED`	The subtask failed with an exception.
`SUCCESS`	The subtask completed successfully.
`UNAVAILABLE`	The subtask result or exception is not available.

Method Summary

Modifier and Type	Method	Description
`static StructuredTaskScope.Subtask.State^PREVIEW`	`valueOf(String name)`	Returns the enum constant of this class with the specified name.
`static StructuredTaskScope.Subtask.State^PREVIEW[]`	`values()`	Returns an array containing the constants of this enum class, in the order they are declared.

Methods declared in class Enum

clone, compareTo, describeConstable, equals, finalize, getDeclaringClass, hashCode, name, ordinal, toString, valueOf

Modifier and Type	Method	Description
`protected final Object`	`clone()`	Throws CloneNotSupportedException.
`final int`	`compareTo(StructuredTaskScope.Subtask.State^PREVIEW o)`	Compares this enum with the specified object for order.
`final Optional<Enum.EnumDesc<StructuredTaskScope.Subtask.State^PREVIEW>>`	`describeConstable()`	Returns an enum descriptor `EnumDesc` for this instance, if one can be constructed, or an empty `Optional` if one cannot be.
`final boolean`	`equals(Object other)`	Returns true if the specified object is equal to this enum constant.
`protected final void`	`finalize()`	Deprecated, for removal: This API element is subject to removal in a future version. Finalization has been deprecated for removal.

`final int`	`hashCode()`	Returns a hash code for this enum constant.
`final String`	`name()`	Returns the name of this enum constant, exactly as declared in its enum declaration.
`final int`	`ordinal()`	Returns the ordinal of this enumeration constant (its position in its enum declaration, where the initial constant is assigned an ordinal of zero).
`String`	`toString()`	Returns the name of this enum constant, as contained in the declaration.
`static <T extends Enum<T>> T`	`valueOf(Class<T> enumClass, String name)`	Returns the enum constant of the specified enum class with the specified name.

getClass, notify, notifyAll, wait, wait, wait

Modifier and Type	Method	Description
`final Class<?>`	`getClass()`	Returns the runtime class of this `Object`.
`final void`	`notify()`	Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()`	Wakes up all threads that are waiting on this object's monitor.
`final void`	`wait()`	Causes the current thread to wait until it is awakened, typically by being notified or interrupted.
`final void`	`wait(long timeoutMillis)`	Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis, int nanos)`	Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.

Enum Constant Details

UNAVAILABLE

public static final StructuredTaskScope.Subtask.StatePREVIEW UNAVAILABLE

The subtask result or exception is not available. This state indicates that the subtask was forked but has not completed, the subtask was forked after the scope was cancelled, or the subtask completed after the scope was cancelled.

SUCCESS

public static final StructuredTaskScope.Subtask.StatePREVIEW SUCCESS

The subtask completed successfully. If the scope is cancelled, the subtask completed successfully before the scope was cancelled. The Subtask.get()^PREVIEW method can be used to get the result. This is a terminal state.

FAILED

public static final StructuredTaskScope.Subtask.StatePREVIEW FAILED

The subtask failed with an exception. If the scope is cancelled, the subtask failed before the scope was cancelled. The Subtask.exception()^PREVIEW method can be used to get the exception. This is a terminal state.

Method Details

values

public static StructuredTaskScope.Subtask.StatePREVIEW[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:: an array containing the constants of this enum class, in the order they are declared

valueOf

public static StructuredTaskScope.Subtask.StatePREVIEW valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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:: IllegalArgumentException - if this enum class has no constant with the specified name; NullPointerException - if the argument is null
