Enum Constant Detail

cascadeWhenOrphan

public static final PropagationConstraint.DeleteConstraint cascadeWhenOrphan

When the source entity is deleted, the target entity is also deleted, but only if it has no other incoming relations.

cascade

public static final PropagationConstraint.DeleteConstraint cascade

When the source entity is deleted, the relation and its target entity are also deleted.

keep

public static final PropagationConstraint.DeleteConstraint keep

When the source entity is deleted, the relation is deleted, but the target entity is preserved.

Method Detail

values

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

Returns:

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

valueOf

public static PropagationConstraint.DeleteConstraint 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
