All Implemented Interfaces:

Serializable, Comparable<SynchronizationType>

public enum SynchronizationType
extends Enum<SynchronizationType>

Specifies whether the persistence context is always automatically synchronized with the current transaction or whether the persistence context must be explicitly joined to the current transaction by means of the EntityManager.joinTransaction() method.

Enum Constant Detail

SYNCHRONIZED

public static final SynchronizationType SYNCHRONIZED

Persistence context is automatically synchronized with the current transaction

UNSYNCHRONIZED

public static final SynchronizationType UNSYNCHRONIZED

Persistence context must be explicitly joined to the current transaction

Method Detail

values

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

Returns:

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

valueOf

public static SynchronizationType 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
