Enum Constant Summary

Enum Constants

Enum Constant and Description
EXISTS Status indicating the value was found in the cache, but exists with a different CAS value than expected.
NOT_FOUND Status indicating the value was not found in the cache (an add operation may be issued to store the value).
OBSERVE_ERROR_IN_ARGS Status indicating there was an error in specifying the arguments for the Observe.
OBSERVE_MODIFIED Status indicating the CAS operation succeeded but the value was subsequently modified during Observe.
OBSERVE_TIMEOUT Status indicating there was a Timeout in the Observe operation.
OK Status indicating that the CAS was successful and the new value is stored in the cache.

Enum Constant Detail

OK

public static final CASResponse OK

Status indicating that the CAS was successful and the new value is stored in the cache.

NOT_FOUND

public static final CASResponse NOT_FOUND

Status indicating the value was not found in the cache (an add operation may be issued to store the value).

EXISTS

public static final CASResponse EXISTS

Status indicating the value was found in the cache, but exists with a different CAS value than expected. In this case, the value must be refetched and the CAS operation tried again.

OBSERVE_ERROR_IN_ARGS

public static final CASResponse OBSERVE_ERROR_IN_ARGS

Status indicating there was an error in specifying the arguments for the Observe.

OBSERVE_MODIFIED

public static final CASResponse OBSERVE_MODIFIED

Status indicating the CAS operation succeeded but the value was subsequently modified during Observe.

OBSERVE_TIMEOUT

public static final CASResponse OBSERVE_TIMEOUT

Status indicating there was a Timeout in the Observe operation.

Method Detail

values

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

Returns:

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

valueOf

public static CASResponse valueOf(java.lang.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:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null
