Enum Constant Summary

Enum Constants

Enum Constant	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

Modifier and Type	Method	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.

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
