Enum Querier.Mode

java.lang.Object

java.lang.Enum<Querier.Mode>

com.yahoo.bullet.querying.Querier.Mode

All Implemented Interfaces:

Serializable, Comparable<Querier.Mode>

Enclosing class:

Querier

public static enum Querier.Mode
extends Enum<Querier.Mode>

This is used to determine if this operates in partitioned mode or not. If the Querier is operating in PARTITION, it is assumed there are multiple queriers running in parallel and consuming parts of the data for the query. Use this if you are distributing the Querier.consume(BulletRecord) calls across multiple machines. This fixes the semantics of the Querier.reset() and the Querier.isClosed() methods to keep the correct windowing semantics. If you are not distributing the data or recreating the querier instance in your parallelized step, you can leave this at the default of ALL.

Method Detail

values

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

Returns:

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

valueOf

public static Querier.Mode 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
