Enum Constant Detail

NO_LOCK

public static final TxKeyLockType NO_LOCK

Transaction doesn't hold lock for given key.

AWAITS_LOCK

public static final TxKeyLockType AWAITS_LOCK

Transaction is enqueued to acquire lock for given key.

OWNS_LOCK

public static final TxKeyLockType OWNS_LOCK

Transaction is exclusive lock owner for given key.

Method Detail

values

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

Returns:

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

valueOf

public static TxKeyLockType 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

fromOrdinal

@Nullable
public static @Nullable TxKeyLockType fromOrdinal(int ord)

Efficiently gets enumerated value from its ordinal.

Parameters:

ord - Ordinal value.

Returns:

Enumerated value or null if ordinal out of range.
