枚举 DecodeEvent

java.lang.Object

java.lang.Enum<DecodeEvent>

ohos.media.image.common.DecodeEvent

所有已实现的接口:

Serializable, Comparable<DecodeEvent>

public enum DecodeEvent
extends Enum<DecodeEvent>

Enumerates the events during the decoding process. It should be in sync with native definition.

枚举常量概要

枚举常量

枚举常量	说明
EVENT_COMPLETE_DECODE	Indicates that decoding is complete.
EVENT_HEADER_DECODE	Indicates that the file header has been decoded.
EVENT_LAST	Indicates the end of the event list.
EVENT_PARTIAL_DECODE	Indicates that partial decoding is complete.

方法概要

限定符和类型	方法	说明
static DecodeEvent	getDecodeEvent(int val)	Creates a DecodeEvent instance based on the passed enum value.
int	getValue()	Obtains the value of this enum.
static DecodeEvent	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 DecodeEvent[]	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 (DecodeEvent c : DecodeEvent.values()) System.out.println(c);

方法详细资料

values

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

getDecodeEvent

public static DecodeEvent getDecodeEvent(int val)

Creates a DecodeEvent instance based on the passed enum value.

参数:

val - Indicates the enum value of the event.

返回:

Returns the created DecodeEvent.
