方法详细资料

values

public static MqttReasonCodes.SubAck[] 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 (MqttReasonCodes.SubAck c : MqttReasonCodes.SubAck.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 MqttReasonCodes.SubAck valueOf(java.lang.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:

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

java.lang.NullPointerException - 如果参数为空值

byteValue

public byte byteValue()

返回:

the value number corresponding to the constant.

valueOf

public static MqttReasonCodes.SubAck valueOf(byte b)

参数:

b - the number to decode.

返回:

the enum value corresponding to the number.
