jline.lang.constant.BalkingStrategy

All Implemented Interfaces:

Serializable, Comparable<BalkingStrategy>, java.lang.constant.Constable

public enum BalkingStrategy
extends Enum<BalkingStrategy>
implements Serializable

Constants for specifying balking strategies (customer refusal to join queue). Balking occurs when a customer arrives at a queue but decides not to join. The decision can be based on: - QUEUE_LENGTH: Balking probability depends on current queue length - EXPECTED_WAIT: Balking probability depends on expected waiting time - COMBINED: Both conditions are evaluated (OR logic - balk if either triggers) ID values match MATLAB BalkingStrategy constants.

Enum Constant Details

QUEUE_LENGTH

public static final BalkingStrategy QUEUE_LENGTH

Balking based on queue length. Uses thresholds mapping queue length ranges to balking probabilities. Example: balk with 50% probability when queue length is between 5-10.

EXPECTED_WAIT

public static final BalkingStrategy EXPECTED_WAIT

Balking based on expected waiting time. Customer estimates waiting time and balks if it exceeds their patience threshold. Requires knowledge of service rate for estimation.

COMBINED

public static final BalkingStrategy COMBINED

Combined balking strategy. Customer balks if EITHER the queue-length threshold OR expected-wait condition triggers. Provides flexibility for complex balking behaviors.

Method Details

values

public static BalkingStrategy[] 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 BalkingStrategy 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

getID

public int getID()

Get the numeric ID for this balking strategy. IDs match MATLAB BalkingStrategy constants.

Returns:

numeric ID

fromID

public static BalkingStrategy fromID(int id)

Convert numeric ID to BalkingStrategy enum value.

Parameters:

id - numeric balking strategy ID

Returns:

corresponding BalkingStrategy enum value

Throws:

IllegalArgumentException - if ID is not recognized

toText

public static String toText(BalkingStrategy strategy)

Convert BalkingStrategy to human-readable text.

Parameters:

strategy - the balking strategy

Returns:

text description
