All Implemented Interfaces:: Serializable, Comparable<PersistenceContextType>

public enum PersistenceContextType
extends Enum<PersistenceContextType>
extends Enum<PersistenceContextType>

Specifies whether a transaction-scoped or extended persistence context is to be used in PersistenceContext. If the type element is not specified, a transaction-scoped persistence context is used.

Since:: Java Persistence 1.0

Method Detail

values

public static final PersistenceContextType[] values()

Returns an array containing the constants of this enum type, in the order they're declared. This method may be used to iterate over the constants as follows:

for(PersistenceContextType c : PersistenceContextType.values())
        System.out.println(c);

Returns:: an array containing the constants of this enum type, in the order they're declared

valueOf

public static PersistenceContextType 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
