Enum Constant Detail

WRITE

public static final LockType WRITE

Exclusive write lock.

Asynchronously flushes enclosed changes to the Terracotta Server Array.

SYNCHRONOUS_WRITE

public static final LockType SYNCHRONOUS_WRITE

Exclusive write lock.

Synchronously flushes enclosed changes to the Terracotta Server Array, blocking the unlocking thread until changes have been acknowledged as committed.

READ

public static final LockType READ

Shared read lock.

CONCURRENT

public static final LockType CONCURRENT

Shared write lock.

No-op lock level that provides no exclusion guarantees, but does provide transaction boundaries. Use at your own risk.

Method Detail

values

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

Returns:

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

valueOf

public static LockType 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
