Enum Constant Detail

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.

Method Detail

values

public static QuotaScope[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (QuotaScope c : QuotaScope.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static QuotaScope valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
