All Implemented Interfaces:

Serializable, Comparable<Locking>

public enum Locking
extends Enum<Locking>

Enumeration of blocking techniques.

Enum Constant Summary

Enum Constants

Enum Constant and Description
SPIN Spin lock blocking is good for locks held very shortly or generally uncontended locks and is therefore the default.
SUSPEND Blocking that suspends a thread and notifies a thread to wake up can be more expensive then spin locks.

Method Summary

Modifier and Type	Method and Description

Enum Constant Detail

SPIN

public static final Locking SPIN

Spin lock blocking is good for locks held very shortly or generally uncontended locks and is therefore the default.

SUSPEND

public static final Locking SUSPEND

Blocking that suspends a thread and notifies a thread to wake up can be more expensive then spin locks.

Method Detail

values

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

Returns:

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

valueOf

public static Locking 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
