Enum Constant Summary

Enum Constants
Enum Constant and Description
`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

Methods
Modifier and Type	Method and Description
`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.

    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.

```
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
