Enum Constants

Enum Constant and Description
GENERATOR Use an IdGenerator to generate the identity (prior to insert).
IDENTITY Use a Database Identity (autoincrement) to generate the identity.
SEQUENCE Use a Database sequence to generate the identity.

Enum Constant Detail

IDENTITY

public static final IdType IDENTITY

Use a Database Identity (autoincrement) to generate the identity.

SEQUENCE

public static final IdType SEQUENCE

Use a Database sequence to generate the identity.

Note: Some databases support getGeneratedKeys with sequences and this then does not involve an extra statement to return the id.

GENERATOR

public static final IdType GENERATOR

Use an IdGenerator to generate the identity (prior to insert).

Note: There is a IdGenerator for UUID's and it is automatically assigned to id properties of type UUID.

Method Detail

values

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

Returns:

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

valueOf

public static IdType 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
