Enum Constant Summary

Enum Constants

Enum Constant and Description
AUTO Defines that PERSIST and/or UPDATE cascading should be applied based on the element type and the availability of a setter.
DELETE Defines that when the declaring type of an attribute is deleted, elements of the attribute are deleted as well.
PERSIST Defines that new elements should be persisted.
UPDATE Defines that existing elements should be updated.

Enum Constant Detail

AUTO

public static final CascadeType AUTO

Defines that PERSIST and/or UPDATE cascading should be applied based on the element type and the availability of a setter. Whether DELETE cascading is activated is determined based on the entity mapping.

PERSIST

public static final CascadeType PERSIST

Defines that new elements should be persisted.

UPDATE

public static final CascadeType UPDATE

Defines that existing elements should be updated.

DELETE

public static final CascadeType DELETE

Defines that when the declaring type of an attribute is deleted, elements of the attribute are deleted as well. Note that this cascading type is redundant if UpdatableMapping.orphanRemoval() is active for the attribute or when the attribute is an inverse attribute. The MappingInverse.removeStrategy() defines how the deletion is done.

Method Detail

values

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

Returns:

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

valueOf

public static CascadeType 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
