Enum LazyCollectionOption

java.lang.Object

java.lang.Enum<LazyCollectionOption>

org.hibernate.annotations.LazyCollectionOption

All Implemented Interfaces:

Serializable, Comparable<LazyCollectionOption>

@Deprecated
public enum LazyCollectionOption
extends Enum<LazyCollectionOption>

Deprecated.

• Use the JPA-defined FetchType.EAGER instead of LazyCollection(FALSE).
• Use static methods of Hibernate, for example Hibernate.size(Collection), Hibernate.contains(Collection, Object), Hibernate.get(Map, Object), or Hibernate.remove(Map, Object) instead of LazyCollection(EXTRA).

Enumerates the options for lazy loading of a collection, many to one association, or many to many association.

Enum Constant Detail

FALSE

@Deprecated
public static final LazyCollectionOption FALSE

Deprecated.

use FetchType.EAGER

The collection is always loaded eagerly, and all its elements are available immediately. However, access to the collection is still mediated by an instance of PersistentCollection, which tracks modifications to the collection.

TRUE

@Deprecated
public static final LazyCollectionOption TRUE

Deprecated.

use FetchType.LAZY

The underlying Java collection is proxied by an instance of PersistentCollection and lazily fetched when a method of the proxy is called. All elements of the collection are retrieved at once.

EXTRA

@Deprecated
public static final LazyCollectionOption EXTRA

Deprecated.

use operations of Hibernate

The underlying Java collection is proxied by an instance of PersistentCollection and its state is fetched lazily from the database as needed, when methods of the proxy are called. When reasonable, the proxy will avoid fetching all elements of the collection at once.

Method Detail

values

public static LazyCollectionOption[] values()

Deprecated.

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 (LazyCollectionOption c : LazyCollectionOption.values())
    System.out.println(c);

Returns:

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

valueOf

public static LazyCollectionOption valueOf(String name)

Deprecated.

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
