Enum Constant Summary

Enum Constants

Enum Constant	Description
INNERTHREADPOOL	Uses a thread pool at the inner level (i.e., the whole thread pool works on each prediction).
STREAMS	Uses the streams API for parallelism when scoring a batch of predictions.
THREADPOOL	Uses a thread pool at the outer level (i.e., one thread per prediction).

Method Summary

Method Details

values

public static KNNModel.Backend[] values()

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

Returns:

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

valueOf

public static KNNModel.Backend 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
