枚举 TaskPriority

java.lang.Object

java.lang.Enum<TaskPriority>

ohos.app.dispatcher.task.TaskPriority

所有已实现的接口:

Serializable, Comparable<TaskPriority>

public enum TaskPriority
extends Enum<TaskPriority>

Specifies the priority of all tasks in a specific task dispatcher when the task dispatcher is being obtained or created.

TaskPriority is designed to ensure better responsiveness for applications. By default, all tasks posted using #getUITaskDispatcher are run with the HIGH priority. To run tasks that do not need to wait for the result, you can adopt the LOW priority.

枚举常量概要

枚举常量

枚举常量	说明
DEFAULT	Indicates the default task priority.
HIGH	Indicates the highest task priority.
LOW	Indicates the low task priority.

方法概要

限定符和类型	方法	说明
static TaskPriority	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 TaskPriority[]	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 (TaskPriority c : TaskPriority.values()) System.out.println(c);

枚举常量详细资料

HIGH

public static final TaskPriority HIGH

Indicates the highest task priority. Tasks with this priority are executed before other tasks.

DEFAULT, LOW

DEFAULT

public static final TaskPriority DEFAULT

Indicates the default task priority. Tasks with this priority are executed after those with the HIGH priority are complete.

从以下版本开始:

另请参阅:

HIGH, LOW

LOW

public static final TaskPriority LOW

Indicates the low task priority. Tasks with this priority are executed after those with the HIGH or DEFAULT priority are complete.

方法详细资料

values

public static TaskPriority[] 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 (TaskPriority c : TaskPriority.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 TaskPriority 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
