Method Summary

Modifier and Type	Method	Description
boolean	consistentOnFailure()	If true, on CAS or PUE failure other than a CheckAndSetException or a KeyAlreadyExistsException, the values may or may not have been persisted but the state is guaranteed to be consistent: any subsequent reads will be repeatable.
boolean	supportsCheckAndSetOperations()	If false, this KeyValueService does not support check and set operations.
boolean	supportsDetailOnFailure()	If false, there are no guarantees that a CheckAndSetException.getActualValues() or KeyAlreadyExistsException.getExistingKeys() from exceptions thrown by the the KeyValueService will actually return any meaningful data (other than the fact that the operation failed).
static CheckAndSetCompatibility.Unsupported	valueOf(String name)	Returns the enum constant of this type with the specified name.
static CheckAndSetCompatibility.Unsupported[]	values()	Returns an array containing the constants of this enum type, in the order they are declared.

Method Detail

values

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

Returns:

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

valueOf

public static CheckAndSetCompatibility.Unsupported 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

supportsCheckAndSetOperations

public boolean supportsCheckAndSetOperations()

Description copied from interface: CheckAndSetCompatibility

If false, this KeyValueService does not support check and set operations.

Specified by:

supportsCheckAndSetOperations in interface CheckAndSetCompatibility

supportsDetailOnFailure

public boolean supportsDetailOnFailure()

Description copied from interface: CheckAndSetCompatibility

If false, there are no guarantees that a CheckAndSetException.getActualValues() or KeyAlreadyExistsException.getExistingKeys() from exceptions thrown by the the KeyValueService will actually return any meaningful data (other than the fact that the operation failed). This method should only be called if CheckAndSetCompatibility.supportsCheckAndSetOperations() is true. If it is not true, behaviour is undefined.

Specified by:

supportsDetailOnFailure in interface CheckAndSetCompatibility

consistentOnFailure

public boolean consistentOnFailure()

Description copied from interface: CheckAndSetCompatibility

If true, on CAS or PUE failure other than a CheckAndSetException or a KeyAlreadyExistsException, the values may or may not have been persisted but the state is guaranteed to be consistent: any subsequent reads will be repeatable. If false, the value may have been persisted in a way that subsequent reads are not repeatable: if a read before the operation could have returned values from a set S, it can non-deterministically return a value from S U {newValue} afterwards. This method should only be called if CheckAndSetCompatibility.supportsCheckAndSetOperations() is true. If it is not true, behaviour is undefined.
