Enum Constant Detail

LOCK_FAILURE

public static final ResponseCode LOCK_FAILURE

Indicates that a lock acquisition attempt failed.

UNLOCK_FAILURE

public static final ResponseCode UNLOCK_FAILURE

Indicates that a lock release attempt failed.

IOEXCEPTION

public static final ResponseCode IOEXCEPTION

TXOP_FAILURE

public static final ResponseCode TXOP_FAILURE

Indicates that an individual transaction operation failed.

COMMIT_FAILURE

public static final ResponseCode COMMIT_FAILURE

A commit failed either because of IO or other failures or because the transaction was already aborted. Attempting either a commit (again) or an abort in response to a commit failure is safe. If the commit failed because the transaction was already aborted, it is best to do nothing.

ABORT_FAILURE

public static final ResponseCode ABORT_FAILURE

An abort failed either because of IO or other failures or because the transaction was already committed. Attempting either a commit (again) or an abort in response to a commit failure is safe. If the abort failed because the transaction was already committed, it is best to do nothing.

Method Detail

values

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

Returns:

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

valueOf

public static ResponseCode 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
