枚举 ContinuationState

java.lang.Object

java.lang.Enum<ContinuationState>

ohos.aafwk.ability.ContinuationState

所有已实现的接口:

Serializable, Comparable<ContinuationState>

public enum ContinuationState
extends Enum<ContinuationState>

Enumerates the migration states of an Ability that has implemented IAbilityContinuation and is in a reversible migration process that allows the ability to be migrated back.

The following example describes state changes in a migration process:

The initial state of FooAbility on device A is LOCAL_RUNNING. If it is migrated to device B in a reversible way, its state on device A becomes REMOTE_RUNNING and that on device B becomes REPLICA_RUNNING. If it is migrated to device B in a non-reversible way, its states on both devices are LOCAL_RUNNING.

枚举常量概要

枚举常量

枚举常量	说明
LOCAL_RUNNING	Indicates that the ability is running on the local device.
REMOTE_RUNNING	Indicates that the ability has been migrated to another device.
REPLICA_RUNNING	Indicates that the ability was migrated from another device to the current device.

方法概要

限定符和类型	方法	说明
static ContinuationState	valueOf(String name)	返回带有指定名称的该类型的枚举常量。 字符串必须与用于声明该类型的枚举常量的 标识符完全匹配。(不允许有多余 的空格字符。)
static ContinuationState[]	values()	按照声明该枚举类型的常量的顺序, 返回 包含这些常量的数组。该方法可用于迭代 常量, 如下所示: for (ContinuationState c : ContinuationState.values()) System.out.println(c);

方法详细资料

values

public static ContinuationState[] values()

按照声明该枚举类型的常量的顺序, 返回 包含这些常量的数组。该方法可用于迭代 常量, 如下所示:

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

返回:

按照声明该枚举类型的常量的顺序返回的包含这些常量的数组

valueOf

public static ContinuationState valueOf(String name)

返回带有指定名称的该类型的枚举常量。 字符串必须与用于声明该类型的枚举常量的 标识符完全匹配。(不允许有多余 的空格字符。)

参数:

name - 要返回的枚举常量的名称。

返回:

返回带有指定名称的枚举常量

抛出:

IllegalArgumentException - 如果该枚举类型没有带有指定名称的常量

NullPointerException - 如果参数为空值
