java.lang.Object

java.lang.Enum<EventHandler.Priority>

ohos.eventhandler.EventHandler.Priority

所有已实现的接口:

Serializable, Comparable<EventHandler.Priority>

封闭类:

枚举常量概要

枚举常量

枚举常量	说明
HIGH	Events with this priority are dispatched before low-priority events.
IDLE	Events with this priority are dispatched only when there are no other events to dispatch.
IMMEDIATE	Events with this priority are dispatched immediately.
LOW	Default priority of an event; events with this priority are dispatched after high-priority events.

方法概要

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

枚举常量详细资料

IMMEDIATE

public static final EventHandler.Priority IMMEDIATE

Events with this priority are dispatched immediately.

HIGH

public static final EventHandler.Priority HIGH

Events with this priority are dispatched before low-priority events.

LOW

public static final EventHandler.Priority LOW

Default priority of an event; events with this priority are dispatched after high-priority events.

IDLE

public static final EventHandler.Priority IDLE

Events with this priority are dispatched only when there are no other events to dispatch.

方法详细资料

values

public static EventHandler.Priority[] 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 (EventHandler.Priority c : EventHandler.Priority.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 EventHandler.Priority 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
