    java.lang.Object
      java.lang.Enum<CycleDetectingLockFactory.Policies>
          com.google.common.util.concurrent.CycleDetectingLockFactory.Policies

All Implemented Interfaces:
  CycleDetectingLockFactory.Policy, Serializable, Comparable<CycleDetectingLockFactory.Policies>

Enclosing class:
  CycleDetectingLockFactory

    @Beta
    public static enum CycleDetectingLockFactory.Policies

extends Enum<CycleDetectingLockFactory.Policies>
implements CycleDetectingLockFactory.Policy

Pre-defined `CycleDetectingLockFactory.Policy` implementations.

Since:
  13.0

Enum Constant Summary
`DISABLED` Disables cycle detection.
`THROW` When potential deadlock is detected, this policy results in the throwing of the `PotentialDeadlockException` indicating the potential deadlock, which includes stack traces illustrating the cycle in lock acquisition order.
`WARN` When potential deadlock is detected, this policy results in the logging of a `Level.SEVERE` message indicating the potential deadlock, which includes stack traces illustrating the cycle in lock acquisition order.

Method Summary
`static CycleDetectingLockFactory.Policies` `valueOf(String name)` Returns the enum constant of this type with the specified name.
`static CycleDetectingLockFactory.Policies[]` `values()` Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

### THROW

    public static final CycleDetectingLockFactory.Policies THROW

  When potential deadlock is detected, this policy results in the throwing of the `PotentialDeadlockException` indicating the potential deadlock, which includes stack traces illustrating the cycle in lock acquisition order.

### WARN

    public static final CycleDetectingLockFactory.Policies WARN

  When potential deadlock is detected, this policy results in the logging of a `Level.SEVERE` message indicating the potential deadlock, which includes stack traces illustrating the cycle in lock acquisition order.

### DISABLED

    public static final CycleDetectingLockFactory.Policies DISABLED

  Disables cycle detection. This option causes the factory to return unmodified lock implementations provided by the JDK, and is provided to allow applications to easily parameterize when cycle detection is enabled.

  Note that locks created by a factory with this policy will not participate the cycle detection performed by locks created by other factories.

Method Detail

### values

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

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

### valueOf

    public static CycleDetectingLockFactory.Policies 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
