枚举常量详细资料

CLUSTER

public static final QuotaScope CLUSTER

The specified throttling rules will be applied at the cluster level. A limit of 100req/min means 100req/min in total. If you execute 50req on a machine and then 50req on another machine then you have to wait your quota to fill up.

MACHINE

public static final QuotaScope MACHINE

The specified throttling rules will be applied on the machine level. A limit of 100req/min means that each machine can execute 100req/min.

方法详细资料

values

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