Enum Constant Detail

FIXED_WINDOW

public static final QuotaAlgorithm FIXED_WINDOW

FIXED_WINDOW The fixed window approach can allow 2x peak specified rate, whereas the rolling-window doesn't.

ROLLING_WINDOW

public static final QuotaAlgorithm ROLLING_WINDOW

ROLLING_WINDOW The rolling window algorithm's additional precision comes at the cost of increased redis resource usage.

Method Detail

values

public static QuotaAlgorithm[] 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 (QuotaAlgorithm c : QuotaAlgorithm.values())
    System.out.println(c);

Returns:

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

valueOf

public static QuotaAlgorithm 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
