方法详细资料
values
public static RegistrationPolicy[] 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 (RegistrationPolicy c : RegistrationPolicy.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 RegistrationPolicy 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
