Enum Constant Detail

TABLE

public static final GenerationType TABLE

Indicates that the persistence provider must assign primary keys for the entity using an underlying database table to ensure uniqueness.

SEQUENCE

public static final GenerationType SEQUENCE

Indicates that the persistence provider must assign primary keys for the entity using a database sequence.

IDENTITY

public static final GenerationType IDENTITY

Indicates that the persistence provider must assign primary keys for the entity using a database identity column.

AUTO

public static final GenerationType AUTO

Indicates that the persistence provider should pick an appropriate strategy for the particular database. The AUTO generation strategy may expect a database resource to exist, or it may attempt to create one. A vendor may provide documentation on how to create such resources in the event that it does not support schema generation or cannot create the schema resource at runtime.

UUID36

public static final GenerationType UUID36

UUID_ANY

public static final GenerationType UUID_ANY

A Any length UUID

SORTED_UUID

public static final GenerationType SORTED_UUID

A sorted UUID

Method Detail

values

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

Returns:

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

valueOf

public static GenerationType 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
