Class PersistentArrayHolder<E>

java.lang.Object
- org.hibernate.collection.spi.AbstractPersistentCollection<E>
- - org.hibernate.collection.spi.PersistentArrayHolder<E>

All Implemented Interfaces:
Serializable,LazyInitializable,PersistentCollection<E>
```
@Incubatingpublic classPersistentArrayHolder<E>extendsAbstractPersistentCollection<E>
```
A dummy collection wrapper for an array. Lazy initialization isnot supported. The use of arrays to represent persistent collections in Hibernate is discouraged.

API Note:
Incubating in terms of making this non-internal. These contracts will be getting cleaned up in following releases.
