Enum EventType

java.lang.Object

java.lang.Enum<EventType>

org.hibernate.generator.EventType

All Implemented Interfaces:

Serializable, Comparable<EventType>

public enum EventType
extends Enum<EventType>

Enumerates event types that can result in generation of a new value. A Generator must specify which events it responds to, by implementing Generator.getEventTypes().

We usually work with sets of event types, even though there are only two types.

Since:

Enum Constant Detail

INSERT

public static final EventType INSERT

An event that occurs when any insert statements needed to persist a new entity instance are executed. This indicates, for example, that a surrogate primary key should be generated, or initial that an initial version number should be seeded.

UPDATE

public static final EventType UPDATE

An event that occurs when any update statements needed to persist changes to a dirty entity instance are executed. This indicates, for example, that a version number should be incremented.

Method Detail

values

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

Returns:

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

valueOf

public static EventType 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
